Page 11: Engine
Components A. Engine (See Manual Drawing #86000601) A 12 volt D.C. electric start, Diesel powered, Deutz Engine drives the hydraulic pump and air compressor. The Vickers variable volume hydraulic pump, which powers the mixer and material pump, is direct coupled to the output shaft of the engine. The air compressor and water pump are belt driven off the engine.
Page 12: Double Drum Mixer
B. Double Drum Mixer (See Manual Drawing #86000585) The SprayMate mixer is a Strong Manufacturing patented Double Drum Mixer, Model Number 2D2.516, with a five cubic foot batch mixing capacity. The mixer consists of two counter rotating paddles turning within two interconnected drums. The paddles have a spiral lead to cause flow of mixed slurry toward discharge end.
Page 13: Progressive Cavity
Note: The engine will not start without the mixer grate in place. A cut off switch breaks electrical power to the engine when the grate is removed. C. Progressive Cavity Slurry Pump (See Manual Drawing #86000499) The material pump is a Strong-Master, open throat, size #60 progressive cavity pump. The material pump forces the slurry through the material hose to a nozzle for spray application.
Page 14 Note: Tighten only enough to correct leakage. Overtightening will cause excessive wear on drive assembly components. If leakage cannot be corrected by tightening bolts, new packing is needed. Replace old packing with new (see manual drawing for packing arrangement). During normal operation, the stator will wear. After excessive wear, the pump pressure will be insufficient to maintain a flow in the material hose to the spray nozzle.
Page 15: Water System
When new, the pump will generate pressures of 200 PSI to 400 PSI. As the pump wears, the capacity to produce the pressure will reduce. When the pump is turning, materials are not discharging from hose and pressure is constant at 200 PSI or less, this is an indication of wear and a new stator or rotor or both may be required.
Page 16: Spray Nozzle
E. Spray Nozzle The spray nozzle converts the flow of materials being pumped into a spray pattern. The air line on the hose connects to the spray nozzle. The air breaks up the flow of materials from the nozzle into a spray pattern when spray tip and cap are in place. The spray pattern can be adjusted by opening or closing the air control valve on the nozzle to achieve the desired pattern.
Page 17: Air
The air hose conveys air to the nozzle. This air is used to break up the flow of material when spraying. This hose has been coupled so that the correct connection is made when coupling. Hose should be inspected daily for damage as a leaking air hose can cause problems. G.
Page 18: Hydraulics
Attach the electrical pig-tail, for the trailer to ensure they are working properly. Check tire inflation as required. For the tires to carry the weight that is required of them, inflate to 55 PSI. If tire pressure is either too high or too low, over-heating will occur and shorten the life of the tires.
Page 19 If the sump strainer becomes clogged, the hydraulic pump will cavitate or run dry and cause severe damage in just a matter of seconds. An increase in noise from the hydraulic when operating under a “No Load” mode, is an indication that pump is cavitating. The machine should be shut down immediately and sump strainer cleaned per instructions in Section IV, part A.
Page 20 Relief Valve The hydraulic pump forces the fluid through a pressure relief valve whose pressure setting has been adjusted to allow the system to produce only enough pressure to do the work. The pressure setting of the SprayMate 35 – D is 2000 PSI. Should pressure requirements exceed 2000 PSI, the relief valve diverts the oil back to the reservoir.
Page 21 1. When changing hydraulic components, take care to keep the system clean of any foreign debris. 2. When trouble in a hydraulic system exists, refer to the “Trouble Shooting Section” labeled Hydraulics, which is included in this manual or call Strong Manufacturing.

Page 23: Machine Set-Up
Operation A. Machine Set-Up Upon arrival at the job site, water supply and accessibility of getting materials to the machine must be taken into consideration when selecting a set up site. Locate the trailer of ground level and downhill from manhole, if possible. Once machine is set up for operation and prior to connecting water or air supply, check to be sure that all guards are in position, the mixer and hopper are free of any foreign objects and that all control valves are is neutral position.
Page 24 Pressure Gauge Assembly Check pressure gauge assembly making sure it is clean and free of foreign debris. Open camlock handles of the 2-inch female quick coupler attach to the bell reducer and attach pressure gauge assembly to the bell reducer. Nozzle Control and Operation The plastic spray tip inserts into the nozzle head and the cap must be fully threaded in place with at least 3 full threads into cap.
Page 25 Caution: At no time should the mixer be in operation without first verifying that the mixer is clear of any foreign objects or debris; and most importantly that all guards are in place. Note: The machine will not operate without the mixer grate in place. The paddle rotation is stopped by moving the control valve lever all the way to the DOWN position.
Page 26: Mixing Procedure
Caution: Never operate pump without slurry or water in hopper. Running the pump dry will cause excessive wear on the stator. Setting Hydraulic Pump for Operation With engine running, turn handwheel on hydraulic pump until hand is pointing at “2”. This initial setting may be increased or decreased to increase or decrease material pumping rate.
Page 27 Pumping Operation With slurry in hopper and material hose connected to pressure gauge, start material pump running in the forward direction. Watch pressure gauge closely while pumping slurry through hose and establishing flow. Should the pumping pressure rise suddenly, stop material pump immediately. Run the pump in reverse until pressure gauge registers “0”...
Page 28: Daily Clean-Up
C. Daily Clean Up The following is the recommended procedure for clean-up of machine, material hose and spray nozzle after operation has been completed for the day. Throughout the day, the machine operator has sufficient time to keep exterior of machine clean of any excessive buildup of material caused by spillage during the mixing operation.
Page 29 in place. Add water to mixer paddles turning and flush all materials out into the hopper and out the discharge door. Rinse out hopper until clean. Close discharge door on hopper and fill with clean water. Disconnect material hose, pressure gauge assembly and bell reducer. Clean out bell reducer, pressure gauge assembly and reconnect to pump.

Page 31: Clean Up
Machine Maintenance Note: No work of any kind should be done on machine without stopping engine, putting all valves in neutral and removing mixer grate. A. Hydraulics Hydraulic return line filter should be changed once a month. Replace with Strong part #0620220. Hydraulic fluid should be changed after first six months of 500 hours or operation, whichever occurs first.
Page 32 nut on the idler sprocket and with a pry bar or hammer, move idler sprocket down until proper tension is achieved. Chain should be oiled lightly once a week. Keys and taper lock bushing Allen screws should be inspected at least once a week to determine condition of keys and to make sure that all Allen screws are tight.
Page 33 hot. When packing gland bottoms out, new packing is required. Refer to pump section of manual for instructions on how to change packing. Pins and connecting rod wear wit use. An indication is slack in connecting rod. Follow procedure outlined in Pumps sections to change components. The pump components wear and will need replacement.
