8.6 Cleaning the air intake grill and engine cooler
It is important to keep the air intake grills and the engine’s other exterior surfaces (including the engine cooler) clean to
allow adequate air intake. An obstructed air intake grill can cause engine damage due to overheating.
CAUTION! Compressed air can cause debris to fly a long distance. Make sure that:
• there are no bystanders;
• you wear eye protection;
• you reduce the compressed air pressure to 210 kPa (30 psi).
Before you begin: Park the machine in a safe location.
1. Open the bonnet.
2. Use compressed air to blow the radiator
clean from the inside out (see the arrow).
3. Use a brush to clean the back of the
radiator.
4. Use a brush or compressed air to clean
the radiator fins.
5. Clean the inside and outside of the
intake grills.
6. Close the bonnet.
8.7 Checking the air resistance indicator
Clean the engine air filter on a daily basis. Regularly check the air resistance indicator to determine if the filter needs
replacing.
Before you begin: Park the machine in a safe location and let the engine cool down.
1. Open the bonnet.
2. Check the air resistance indicator (1).
• If the red plunger in the indicator
is visible, the air filter requires
immediate maintenance.
3. Replace the air filter if necessary.
4. Close the bonnet.
NOTICE The indicator does not work correctly if the indicator housing is cracked or broken.
