1- General Information The Boxxer 318HP is a carefully engineered truckmount designed and manufactured by HydraMaster for hard surface cleaning as well as carpet and upholstery cleaning. The Boxxer 318HP can also be used for high pressure washing applications. The system utilizes an internal combustion engine to provide the power necessary to turn both a blower (also referred to as a vacuum pump) and a high pressure water pump.
If you have any questions regarding the operation, maintenance or repair of this machine, please contact your local distributor. If your question cannot be resolved by your distributor or by the information within this manual, you may contact HydraMaster direct using the following phone numbers. HOURS TELEPHONE NUMBERS...
WARNINGS, CAUTIONS AND NOTICES HydraMaster uses this WARNING symbol throughout the manual to warn of possible injury or death. This CAUTION symbol is used to warn of possible equipment damage. This NOTICE symbol indicates that federal or state regulatory laws may apply, and also emphasizes supplemental information.
Page 12
Transporting a vented fuel container that presently contains, or has ever contained in the past, a flammable liquid is strictly forbidden by HydraMaster and by federal and state regulations. Doing so will increase the risk of fire and explosion. Serious injury or death may result.
Page 13
Never smoke in or around the truckmount. Doing so will increase the risk of fire and explosion. Serious injury or death may result. During the operation of the truckmount the exhaust system will become extremely hot. Keep all flammable materials away from the truckmount exhaust system. Failure to do so will increase the risk of fire and explosion.
Page 14
Never allow water to freeze inside the truckmount. Serious component damage will occur. Perform all freeze guarding procedures outlined in this digital Owner’s Manual. Many vehicles have critical components mounted directly below the floor that can easily be damaged. Before drilling holes in the floor of the vehicle, inspect the underside of the vehicle for critical components.
RESPONSIBILITIES The Purchaser’s Responsibilities Prior to purchasing a van, ensure that the payload is suitable for all of the equipment that will be installed and transported. This includes and is not limited to: the truckmount, recovery tanks, fresh water tanks and any other on-board water, hose reels, hoses, cleaning tools, chemicals, drying equipment, etc.

Hard Water Advisory HydraMaster recognizes that any hard water deposits which might occur within the water system of our truckmounts is a serious problem. The precision technology of truckmount heat exchanger systems is intolerant of any foreign material. Hard water deposits will ultimately decrease the performance of the system and are expected to seriously lower the reliability of the machine.
Cleaning efficiency and equipment life is increased, chemical use decreased, and the appearance of cleaned carpets enhanced when water softeners are incorporated in hard water areas. HydraMaster strongly urges the use of water softener units with the Boxxer 318HP in areas exceeding 3.0 grains per gallon.
Page 22
Access to the sanitary system can be obtained through a toilet, laundry drain, RV dump, etc. Permission should first be obtained from any concerned party or agency. The Boxxer 318HP can be equipped with an optional Automatic Pump-Out System (APO). These systems are designed to remove waste water from the extractor’s recovery system and actively pump the water through hoses to a suitable disposal drain.
Although there are many different heavy duty vehicles used for cleaning equipment, the preferable vehicle for a Boxxer 318HP installation is a tandem axle trailer with a heavy- duty suspension package equivalent to 3/4 ton capacity or a 3/4 ton HD van. If a fresh water tank is added, a one ton or larger capacity van is required.
OPERATING THE BOXXER 318HP IN HOT WEATHER HydraMaster recommends the following steps when operating the Boxxer 318HP during periods of hot weather (95º F or higher). This will help ensure that your Boxxer 318HP continues to run at 100% capacity during even the hottest days.
Figure 2-2. Recommended Location of Boxxer 318HP in Van Secure Installation No matter how the unit is installed, check to see if the Boxxer 318HP is properly secured to the floor of the van with the hardware provided. This safety measure will ensure that the machine will not slide inside the van.
Page 26
A sudden or crash stop will cause the machine to rocket forward if not properly secured. To prevent serious personal injury, ensure that the Boxxer 318HP is well secured to the floor of the vehicle with the hardware supplied. Protect yourself and the machine.
Setting the vacuum level higher than the recommended value can result in an increased risk of serious component damage. The Boxxer 318HP is shipped from the factory with antifreeze added to the solution system. Recover this antifreeze and dispose of the recovered antifreeze as stated in the local laws and regulations.
ORIENTATION OF FUEL PUMP For proper fuel pump operation and fuel flow, the vehicle’s fuel pump must be installed in a lower position with respect to the fuel tank and in as vertical a position as possible (outlet side up - see Figure 2-3 and Figure 2-4).
3 - Cleaning Information The Boxxer 318HP has been engineered using the latest and most sophisticated technology available to produce the finest hard surface cleaning results possible. Despite this, it remains only a tool of the carpet and hard surface cleaning trade and can produce only as a good a job as the person operating it.
Relying on the rinse detergent to do the majority of the cleaning will result in overly long dry times and excess detergent residue left in the carpet. HydraMaster recommends the use of our pre-sprays: Fastbreak™ for residential carpet and Blitz™ for commercial carpet needs.
For more information about HydraMaster’s complete chemical product line, visit this webpage: http://hydramaster.com/Products/Chemicals.aspx OVERWETTING Overwetting is an annoyance to all concerned. Extended drying times will leave the customer with a negative impression of both the cleaning company and the process used.
SEVERE CLEANING SITUATIONS When your truckmount is used for hard-surface cleaning or pressure washing, some jobs may involve severe cleaning situations. In these cases, certain precautions will need to be taken in order to ensure that the recovery tank and various internal components are not damaged The following are examples of severe cleaning situations.
Page 33
Use of the vacuum recovery system for “dry cleaning”, without corresponding solution application (i.e. duct cleaning), is specifically excluded as an approved use of the truckmount. Failure to follow this exclusion may lead to component failure and will invalidate your warranty. If concentrated acids or solvents are used to pre-treat surfaces before power washing, do not recover them through the vacuum system.
CLEANING TOOL TIPS Wands With a wand, keep cleaning strokes short, front to back, and run a “dry pass”. After pulling the wand for a strip of 3 or 4 ft long with the solution trigger activated, go back up to the top of the stroke, and make a “dry “ pass [i.e. no solution flowing]. This gives the wand a second chance to pick up the solution on the carpet.
Page 37
Rotary Tools HydraMaster’s selection of Rotary Extraction Tools includes the RX-15H and the RX-20. RX-15H Hard Surface Cleaning Tool The RX-15H can be used to clean tile, concrete and stone floors. Select the appropriate pre-spray and apply to the floor.
Page 38
RX-20 Tool for Carpet, Hard Surface and Bonnet Cleaning Before turning on the RX-20, adjust the handle; it should rest right below or even with the bottom of your pants’ front pockets, with the tool resting flat on the floor. Take your time in adjusting the tool’s height;...
Page 39
Upholstery Tool: DriMaster 3 Use the upholstery tool on small rugs and furniture. When you clean rugs, be sure that the temperature and chemicals are safe for that particular type of rug. As with the larger tools, do not leave the surface of the upholstery too wet. Adjust the volume of water on the tool without it touching any surface: the water should just barely come out of the tool before the vacuum pulls it back in.

To help achieve a high psi rating for high pressure washing, HydraMaster has added a chemical pump shutoff valve into the Boxxer 318HP’s pump system. The shutoff valve can be accessed from the side of the machine (see Figure 4-3).
START-UP PROCEDURE Perform all daily and periodic maintenance as specified in section 5 of this Owner’s Manual. Connect a garden hose to supply water to the truckmount. If used, press the “PUMP-IN” switch to the “ON” position (see Figure 4-1). The water box must be full prior to starting the truckmount.
Page 45
10. Turn the “CHEMICAL PUMP” valve to the “PRIME” position to purge any air from the system. With the truckmount running at full throttle, block off the vacuum intake to the Recovery Tank. The vacuum gauge should read 12” Hg. This will assist in priming the chemical system.
SETTING THE PRESSURE FOR HIGH PRESSURE WASHING OPERATIONS The chemical pump shutoff valve must be turned off during high pressure washing operations. The chemical pump shutoff valve is off when the handle of the integrated valve is perpendicular to the pump (see Figure 4-5). Chemical pump shutoff valve is shown in OFF position here.
Cap off the inlet(s) to the Recovery Tank. Spray a HydraMaster-recommended spray lubricant into the “BLOWER LUBE PORT” for about 5 to 7 seconds while the unit is running (see Figure 4-2). Allow machine to run additional 2 to 5 minutes under load to flush off lubricant.
A maintenance log is provided in the Owner’s Guide. This log must be maintained and may be required to be furnished to HydraMaster before a warranty claim is honored. It is recommended that the log be affixed to the vehicle door near the truckmount for convenience and to serve as a maintenance reminder.
• Inspect the truckmount for water and oil leaks, loose electrical connections, etc. and repair as needed. • Lubricate the blower lube port with HydraMaster-recommended spray lubricant. Weekly Maintenance • Inspect the recovery tank filters for tears, holes, etc. Repair or replace as needed.
500 Hours • Change the blower oil. • Change the high pressure pump oil. • Check the engine valve clearance (intake and exhaust 0.004” - 0.006”) 1000 Hours • Clean the blower heat exchanger. Refer to the Interval Hours Maintenance chart in the Owner’s Guide. OVERALL MACHINE MAINTENANCE Maintenance, troubleshooting and repair are much easier tasks to accomplish on a clean truckmount.
HIGH PRESSURE PUMP MAINTENANCE Daily Check the oil level and the condition of the oil. The oil level should be up to the center of the sight glass on the rear of the pump or between the “MIN” and “MAX” lines on the dipstick.
Valve Maintenance (See Figure 5-1) Using a 22-mm wrench or socket, remove all six valve caps on the manifold of the pump. Examine each valve cap O-ring for cuts or distortions and replace if worn. Using needle nose pliers, remove the suction and delivery check valves. The valve assembly usually stays together when removing.
Page 54
Replace old valves with new valves by placing the assembly in the valve chamber. Press down firmly on the top of the valve assembly. Replace valve caps by applying LOCTITE® 243 to valve cap and torque to 33 ft- lbs. Removing and Replacing Pump Manifold Remove the manifold of the pump by taking a 5-mm Allen head wrench and removing the eight head bolts.
Page 55
Torque to 4.5 ft-lbs. Servicing the Crankcase While the manifold and plungers are removed, rotate the crankshaft by hand. Closely examine the crankcase oil seals for drying, cracking or leaking. Consult the local HydraMaster distributor if crankcase servicing is necessary. 5-7: Machine Maintenance...
Capping off the inlet(s) to the recovery tank. Spraying a HydraMaster-recommended spray lubricant into the “BLOWER LUBE PORT” for about 5 to 7 seconds while the unit is running. Uncapping the inlet(s) and run the unit for another minute to allow the blower to cool down.
DESCALING PROCEDURE (REQUIRED) Scale deposits on the interior of the heating system can cause a noticeable loss in heating performance. Deposits of this kind result from hard water deposits. The frequency with which descaling procedures are required will vary. If the area has particularly hard water, you may have to descale often.
FREEZE GUARDING To avoid permanent damage to the truckmount, it is imperative to follow the freeze guard procedure whenever the possibility of freezing temperatures exists. When disposing of antifreeze follow local laws and regulations. Do not discard into storm sewers, septic systems, or onto the ground. Antifreeze is harmful or fatal if swallowed.
Page 59
The reclaimed antifreeze solution may be used three times before being discarded. To freeze guard the hoses and wand perform step 7 with the items to be freeze guarded attached. Recovering Antifreeze for Re-Use Attach all hoses and wands which have been freeze guarded to the truckmount. Attach the incoming water source to the front of the truckmount.
TENSIONING THE PUMP DRIVE BELT Remove the Boxxer 318HP grill to gain access to the idler pulley. Loosen but do not remove the 2 ¼” long bolt (P/N 000-143-041) on the idler pulley. See page 9-32. Remove the right cover of the machine to gain access to the tensioning screw.
Finally, the water joins the chemical where the solution is created. The chemical is pressurized by the HydraMaster diaphragm chemical pump attached to the head of the water pump. This pump pulls the chemical from the jug through the chemical meter.
Electrical Schematic Wiring Diagram The Boxxer 318HP electrical system operates on 12 V DC which is provided by the battery. Battery levels are maintained by a 20 Amp alternator that is built into the engine. Before a new battery is installed, check that it is properly charged before installation or damage to the charging system may occur.
