before performing maintenance.
CAUTION
Swallowing engine coolant can cause poisoning.

Checking the Cooling System

Service Interval: Before each use or daily
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti freeze. Check the level of
the coolant in the expansion tank at the beginning of each day
before starting the engine. The capacity of the cooling system
is 7.5 liters (6 quarts).
1. Check the level of the coolant in the expansion tank
(Figure 42). The coolant level should be between the
marks on the side of the tank.
2. If coolant level is low, remove the expansion tank cap
and replenish the system. Do not overfill.
3. Install the expansion tank cap.

Cleaning the Radiator

Service Interval: Before each use or daily
To prevent the engine from overheating, the radiator must
be kept clean. Normally, check the radiator daily and, if
necessary, clean any debris off these parts. However, it will
be necessary to check and clean the radiator frequently in
extremely dusty and dirty conditions.
Note: If the attachment or engine shuts off due to
overheating, first check the radiator and the whole radiator
for excessive buildup of debris.
Clean the radiator as follows:
1. Open the hood and secure the prop rod.
2. Loosen the flange nut securing the clean out cover to
the underside of the rear frame
cover to the side to expose the clean out hole in the
frame.
