GENERAL INFORMATION
TRANSPORTING THE MACHINE
CAUTION!
Before transporting the machine on an open truck or trailer, make sure that . . .
•All access doors are latched securely.
• The machine is tied down securely - see tie-down locations (26).
• The machine parking brake is set.
TOWING OR PUSHING A DISABLED MACHINE
CAUTION!
The machine’s drive propelling pump is manufactured with an adjustable tow valve. This valve prevents damage to the hydraulic system when the
machine is being towed/pushed short distances without use of the engine.
To access the valve; unlatch and open the Oil Reservoir / Fuel Tank Cover (20) and then open the Engine Compartment Cover (1) and locate the
hydrostatic pump at the rear of the engine. Turn the valve 90 degrees, this disengages the hydrostatic lock between the motor and pump.
WARNING: The hydraulic propelling pump can be damaged if the machine is towed with the valve in the normal working position (A). Reference
the illustration on the following page for the normal working setting (A) (vertical) and the free wheeling towing setting (B) (horizontal). Note: If the
tow valve is left in free wheeling (B) (horizontal) position the propelling pump can’t drive the machine FWD or REV. No damage will result, just
re-set valve to the normal working setting (A) (vertical). NOTE: Tow or push machine no faster than a normal walking pace (2-3 miles per hour)
and for short distances only. If the machine is to be moved long distances the drive wheel needs to be raised off the oor and placed on a suitable
transport dolly.

MAINTENANCE
ENGINE AIR FILTER
The engine Air Filter (24) is located in the engine compartment. Check the air mechanical vacuum lter Service Indicator (27) before each use of
the machine. Do not service the air lter unless the indicator is shown (red).
CAUTION!
When servicing the engine air lter elements, use extreme caution to prevent dust and dirt from entering the engine.
The engine air lter contains a primary (outer) and a safety (inner) lter element. The primary element may be cleaned twice before being replaced.
Replace the safety element every third time that the primary element is serviced. Never try to clean the safety element. To clean the primary lter
element, remove the cover from the dust cup end of the canister and pull out the primary element. Clean the element with compressed air (maximum
pressure 100 PSI) or wash it with water (maximum pressure 40 PSI). Do not put the element back into the canister until it is completely dry.
Special Service Note: Inspect the complete air intake system for proper routing (kinks & restrictions) and sound tight connections. The mechanic
should run their hand around the air intake hoses to check for any cracks and holes that will allow non-ltered air to enter the engine that will
severely shorten the engine’s useful life.
ENGINE MAINTENANCE (150 HOURS)
At 150 hour intervals it is recommended that the following service be performed: Change oil and lter, clean and inspect spark plugs, check all
engine belts condition and adjustment, check battery charge and level, check cooling system hoses and clamps and check general condition and
performance of engine.
Note: Reference the separately supplied PSI GM Power Train Products Operation and Maintenance manual for more detailed service data. See
the “Other Manuals Available” section for a complete list of the engine manuals that are available.
SPECIAL LIQUID PROPANE FUEL SYSTEM MAINTENANCE ON THE GM 1.6L ENGINE
Every 150 hours inspect and drain any oil build up from the LP fuel system electronic pressure regulator (EPR). During the course of normal
operation oils or “heavy ends” may build inside the chambers of the propane regulator. These oils and heavy ends may be a result of poor fuel
quality, contamination of the fuel supply chain, or regional variation in the make up of the fuel. If the build up of the oil is signicant this can affect
the function of the fuel control system. Note: Reference the Tier 2 PSI 1.6l PFI certied engine service manual form # PSI1P6LPFI-A, and follow
the procedure to drain the EPR regulator.

FORM NO. 56043129 - SR 1900 - 13
MAINTENANCE
HYDRAULIC OIL
WARNING!
To avoid hydraulic oil injection or injury, always wear appropriate clothing and eye protection when working with or near hydraulic
system.
Check the Hydraulic Oil Level. Unlatch and swing open the Oil Reservoir / Fuel tank Cover (20). Remove the reservoir cap to check
the oil level. The hydraulic oil level should be half way up the screen lter inside the ller neck of the reservoir. Add SAE 10W30 motor oil
if it is below this level. Change the oil if major contamination from a mechanical failure occurs.
Change the Hydraulic “Charge” Oil Filter once a year or every 1000 hours.
HOPPER DUST CONTROL FILTER (PANEL FILTER)
The hopper dust control lter must be cleaned regularly to maintain the efciency of the vacuum system. Follow the recommended lter service
intervals for the longest lter life.
CAUTION!
Wear safety glasses when cleaning the lter.
Do not puncture the paper lter.
Clean the lter in a well-ventilated area.
Wear appropriate dust mask to avoid breathing in dust.
Toremovethehopperdustcontrollter...
1 Unlatch and open the Hopper Cover (16). Make sure that the Hopper Cover Prop Rod (17) is in place.
2Inspect the top of the Hopper Dust Control Filter (12) for damage. A large amount of dust on top of the lter is usually caused by a hole in the
lter or a damaged lter gasket.
3 Unthread and remove the four Shaker Assembly Retainer Knobs (13). Lift off the Dust Filter Shaker Assembly (11) to access the panel lter.
4Lift the Hopper Dust Control Filter (12) out of the machine.

Method “A”
Vacuum loose dust from the lter. Then gently tap the lter against a at surface (with the dirty side down) to remove loose dust and dirt.
Method “B”
Vacuum loose dust from the lter. Then blow compressed air (maximum pressure 100 psi) into the clean side of the lter (in the opposite
direction of the airow).
Method “C”
Vacuum loose dust from the lter. Then soak the lter in warm water for 15 minutes, then rinse it under a gentle stream of water (maximum
pressure 40 psi). Let the lter dry completely before putting it back into the machine.
6 Follow the instructions in reverse order to install the lter. If the gasket on the lter is torn or missing, it must be replaced. NOTE: Before
replacing lter clear debris from dust plate located under lter. Verify that the debris ap at the rear of the dust plate swings freely
HOPPER DUST CONTROL FILTER (OPTIONAL NILFISK POCKET FILTER SYSTEM)
The optional Nilsk pocket lter system is basically maintenance free. The only periodic maintenance required by the machine operator is to run the
Shaker (LL) on a daily basis. NOTE: The shaker should only be run with the hopper in the down position.

Functionofthemaincontroller’sserviceindicatorfaultblinkcodedisplaylight
The A2 main controller will out put a ashing fault code to the operator display panel when or if there is a problem (current overloads) associated with
specic electrical low current circuit controller output functions. Examples of circuits; hydraulic solenoid coils used to turn on & off hydraulic loads
and numerous relays used for activating machine function such as the headlights, horn, shaker motor, back-up alarm etc.
See Figure 1. When an A2 controller fault occurs the service indicator light (LED) (UU) will blink (ash) a special fault (error) code sequence until
the fault is corrected. See “Table A” for a description of the fault indications.
Service Note: Instructions on how to read the fault code service indicator light. The service indicator LED blink code should operate as follows:
• First part of code (250mS period per ash – 125mS ON, 125mS OFF the 700mS LED OFF period.
• Second part of the code (250mS period per ash – 125mS ON, 125mS OFF the 700mS LED OFF period.
• 2 second LED off period
• Repeat sequence
If multiple faults are present, the codes should appear in order until all are displayed and then the entire sequence will repeat.
Example: Code1, 2
0 00 0 00 one light blink, a short pause two blinks, long pause and the code will be repeated.
LED on for 125mS
LED off for 700mS
