To thoroughly clean the radiator:
1. Remove the screen.
2. Working from the fan side of the radiator, blow with
low pressure (25 p.s.i.) compressed air (Do Not Use
Water). Repeat procedure from the front of radiator and
again from the fan side.
3. After the radiator is thoroughly cleaned, clean out
debris that may have collected in the channel at the
radiator base.

Changing the Engine Oil And
Filter
Check oil level after each day's operation or each time
machine is used. Change oil and filter initially after first 50
hours of operation; change oil and filter after every 200
hours of operation thereafter. If possible, run engine just
before changing oil because warm oil flows better and
carries more contaminants than cold oil.
1. Position machine on a level surface.
2. Open the hood. Set drain pan under the oil pan and in
line with drain plug (Fig. 37).
3. Clean area around drain plug.

Servicing the Fuel System
Fuel Tank
Drain and clean fuel if tank becomes contaminated or
machine is to be stored for an extended period. Use clean
solvent to flush out the tank.
8. Lubricate gasket on filter canister with clean oil.
9. Install filter canister by hand until gasket contacts
mounting surface, then rotate an additional 1/2 turn.
Replacing Fuel Pre Filter
Replace the fuel pre filter (Fig. 39), located between fuel
tank and fuel pump after every 400 operating hours or
yearly, whichever occurs first.
1. Clamp both fuel lines that connect to the fuel filter so
fuel cannot drain when lines are removed (Fig. 39).
2. Loosen the hose clamps at both ends of the filter and
pull fuel lines off filter.
