R

4.  Never fuel the machine indoors or in an enclosed 

trailer.

5.  Never store the machine or fuel container where 

there is an open flame, spark or pilot light such as on 
a water heater or other appliances.

6.  Never fill containers inside a vehicle or on a truck 

or trailer bed with a plastic liner. Always place 
containers on the ground away from your vehicle 
before filling.

7.  Keep the nozzle in contact with the rim of fuel tank 

or container opening at all times until fueling is 
complete. Do not use a nozzle lock-open device.

8.  If fuel is spilled on clothing, change clothing 

immediately and wash affected skin.

9.  Replace gas cap and tighten securely. 

5.4 ENGINE AIR CLEANER

A. CLEANING AND/OR REPLACING AIR 
CLEANER ELEMENT

For any air cleaner, the operating environment dictates 
the air cleaner service periods. Inspect and clean the 
air cleaner element after every 50 hours of operation or 
monthly, whichever occurs first and replace the element if 
required or every 200 hours. Refer to the Engine Operator’s 
Manual furnished with this truck loader for instructions. 

- NOTE -

In extremely dusty conditions it may be necessary 
to check the element once or twice daily to prevent 
engine damage.

5.2 ENGINE OIL

A. CHECKING ENGINE CRANKCASE OIL LEVEL 

The engine oil level should be checked after every 8 hours 
of operation or daily as instructed in the Engine Operator’s 
Manual furnished with this truck loader.

B. CHANGING ENGINE CRANKCASE OIL

After the first 20 hours of operation, change the engine 
crankcase oil and replace the oil filter. Thereafter, change 
the engine crankcase oil after every 100 hours of operation 
or bi-weekly, whichever occurs first. Refer to the Engine 
Operator’s Manual furnished with this truck loader for 
instructions.

5.3 ENGINE FUEL SYSTEM

 DANGER

To avoid injury from burns, allow the engine 
to cool before removing the fuel tank cap and 
refueling.

A. FILLING THE FUEL TANK

Fill the fuel tank at the beginning of each operating day.  
Fill to approximately 1" below the top of the fuel tank 
(approximately 8-1/2 gallons indicating Full (F) on the fuel 
gauge) at the beginning of each operating day. Do not 
overfill. Use clean, fresh unleaded gasoline with a minimum 
octane rating of 87 and a maximum of 10% Ethanol.

DO NOT use E85 Fuel. Using E85 Fuel will cause severe 
damage to the engine.

To avoid personal injury or property damage, use extreme 
care in handling gasoline. Gasoline is extremely flammable 
and the vapors are explosive.

1.  Extinguish all cigarettes, cigars, pipes and other 

sources of ignition.

2.  Use only an approved gasoline container.

3.  Never remove the gas cap or add fuel with the 

engine running. Allow the engine to completely cool 
before fueling.
