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.

3. Working from the fan side of the radiator, blow out
debris with low pressure (50 psi) compressed air (do
not use water). Repeat the step from the front of the
radiator and again from the fan side.
4. After the radiator is thoroughly cleaned, clean out
debris that may have collected in the channel at the
radiator base and around the frame. Also, clean out
the engine compartment and brake linkage to assure
optimum performance.
5. Close the clean out cover and secure the flange nut.
6. Close the hood.
Note: Do not use water to clean the external surfaces
of the radiator. Use of water will trap and solidify
debris in the recesses of the radiator limiting its ability
to perform as designed.
