TABLE OF CONTENTS Introduction Warnings, Cautions, Notes Operations Maintenance Trouble Shooting Replacement Parts Warranty Guide Schematics Hydraulic Oil MSDS Tire Information Insert Engine Manual Insert IMPORTANT NOTICE! This manual contains cautions and warnings that alert you to potential safety issues. WARNING is used to inform you of conditions or operations that could cause serious injury or death.
Page 7
Before Starting or Operating this Machine Understand and observe all the following Warnings, Cautions, and Notes. WARNINGS This equipment contains mechanical and heating components that may cause serious injury or death if not handled or maintained properly. All personnel must be properly trained in the operation and maintenance of this equipment.
OPERATIONS Basic Operation WARNING: Before refueling, shut off the burners and the engine. CAUTION: Be sure operators have been properly instructed in starting and op- erating all equipment before beginning. NOTE: See following pages for specific instructions on operating burners and heating systems.
Page 11
OPERATIONS Basic Operation 1. Start engine (refer to engine operations). 2. Turn on control box power switch. 3. Load bituminous/asphalt material into kettle using the safety loading chute. Make sure no moisture is present in tank. Be sure to wear proper protective clothing. Flues must be completely covered with 4”...
Page 12
OPERATIONS Basic Operation 12. If necessary, add heated bituminous binding material to the recycler mixing chamber (refer to the plumbing operations chart). Here again, experience is the best indicator of how much to add. Start with gallons of oil. Know the material being added and the flash point. We recommend that you use an AC type oil and add the oil in the first three minutes of the batch timer.

(solvent) in the oil. This makes the material soft and pliable, but also makes them very easy to catch on fire. If you are using the SRM to heat cold patch material, only fire the burner in 1-2 minute cycles and check the temperature very often to prevent the material...
Page 14
OPERATIONS Kettle Heating System WARNING: The burners must be shut off when the product reaches a level approximately 4" above the flues. Exposed flues will overheat causing an explosion in the tank. This will cause equipment damage and possible injury or death to personnel. Before Igniting the Burner: 1.
Page 15
Igniting the Burner: 1. The SRM recycler chamber has two set point temperatures. One “higher firing” set point for heating up the mix, and one “stand-by” temperature setting that keeps the liner and materials at a given temperature. Pressing the “Cycle Start” button changes the max set point to the “higher firing”...

Page 17
Be sure all pre-start checks are complete prior to starting engine. The SRM is equipped with a digital engine management system. This system will shut the en- gine down in case of an engine overheat or low oil pressure. It is also equipped with an hour meter, cold weather glow plug button, and a starting button.
Page 18
OPERATIONS Pumping System WARNING: DO NOT allow flushing solvent to enter hot oil tank or mixer. DO NOT allow the hot oil tank burner to operate with the product level less than 2 inches above the flues. Severe damage to equipment and possible serious injury will result! DO NOT flush through a heated wand.
Page 20
OPERATIONS WPC Valve Hand Wand Wand Pressure Control Valve (WPC Valve) Operators must understand the proper operation of the WPC valve located on the top rear of the unit. The purpose of this valve is to direct the flow of product either back to the tank (during start-up to assist melting) or to the wand (during crack filling or pothole spraying oper- ations).
Page 21
OPERATIONS Heated Hose Heated Hose & Wand (optional) The application hose and wand are equipped with internal heating elements. The elements are powered by the 24 volt alternator run by the engine. This heating element prevents the product from freezing in the hose and wand. The electric wand heat control should be turned on 20 to 30 minutes before trying to pump material through the hose and wand.
Page 22
OPERATIONS Wand Application with Twist-Valve Wand 1. Position the WPC valve midway between the wand and recirculate position. 2. Close the wand flow control valve (located on the wand handle) and remove wand from the recirculating flange. 3. Set product pump to "Pump" position, then open the wand flow control valve to apply prod- uct to the road surface.
Page 23
Pumping System WARNING: The Stepp SRM requires special shut down procedures that must be followed to maximize safety and equipment performance. The procedures will assure that the hose and wand always have product in them to avoid an over-heated element. (Do Not suck the prod- uct back out of the wand and hose assembly) No hose cleanup is necessary as the product in the hose is re-melted at the next start up with the wand and hose heating element.
Page 24
Pumping System Standard Shut Down Procedures for Units With Non-Heated Hose WARNING: The Stepp SRM requires special shut down procedures that must be followed to maximize safety and equipment performance. CAUTION: Set pump to OFF or neutral before adjusting valves.
Page 25
OPERATIONS Helpful Hints 1. It is recommended that the product be drawn down to capacity or less prior to shutdown. This will decrease the start up time the next time the machine is used. How- ever if you are certain the equipment will be used the next day (no chance of rain, etc.), leave the unit about ½...
MAINTENANCE Product Pump Fig. 1 The pump used for hot oil pumping is a gear type pump. Shaft rotation will determine which port is suction and which is discharge. A look at the Fig.1 will show how the fluid will flow through the pump.
Page 29
MAINTENANCE Hot Asphalt Hose Replacement CAUTION: Do not remove hose without first removing the heating element or damage to heating element will result. Hose Removal: 1. Remove heating element from hose (refer to heating element removal procedures). 2. Disconnect all electrical connections from hose. 3.
Page 30
MAINTENANCE Hose Heating Element Replacement (Functioning Element) Hose Heating Element Removal: These instructions assume the heating element is functioning properly. If the heating element does not function, refer to the instructions on the following pages. NOTE: If the hose is damaged, skip steps 1 through 3, activate wand heat for 15 minutes, then begin at step 4.
Page 31
MAINTENANCE Hose Heating Element Replacement (Functioning Element) Hose Heating Element Installation: 1. Remove wand from hose at quick coupling. 2. Lay the hose out as straight as possible. 3. Install new compression fitting into cross fitting. NOTE: If hose DOES NOT contain material proceed with step 4. If hose CONTAINS material, replace step 4 with steps A &...
Page 32
MAINTENANCE Hose Heating Element Replacement (Non-Functioning Element) Hose Heating Element Removal and Installation: These instructions assume the heating element is damaged and NOT functioning. If the heat- ing element functions properly, refer to the instructions on the previous page. The element may be damaged during removal, rendering it useless.
Page 33
MAINTENANCE Wand & Boom Heating Element Replacement Wand or Boom Heating Element Removal and Installation: These instructions assume the heating element is damaged and not functioning. The element may be damaged during removal rendering it useless. A functioning heating element is slid into the wand or boom along side the non-functioning element.
Page 34
MAINTENANCE Pugmill Mixer The SRM has many high torque moving parts. As a weekly inspection, we suggest that the operators check for loose fittings and loose bolts. Outlined below are some that need to be checked periodically due to the torque and vibration that the unit incurs.
Page 35
MAINTENANCE Conveyor The conveyor needs to be inspected daily for wear, and to make sure that the belt is tracking properly. As the belts are used, they will stretch, requiring tightening. 1. Check grease bearings daily (#1). 2. Check belt tension and tracking (#2). To adjust tracking, you must first loosen the 4 nuts on the bearing.
