MAINTENANCE
CLEAN AIR CONDITIONER FRESH/RECIRC FILTERS
If compressed air is used, there is danger that dirt may fly and cause personal injury.
Always wear safety glasses, dust mask, and other protective equipment.
NOTICE
As a guideline, the filters should be cleaned every 500 hours, but on dusty jobsites, clean the filters more
frequently.
REMARK
If the filter becomes clogged, the air flow will be reduced, and there will be an abnormal noise from the air condi-
tioner unit.
Cleaning Reticulated Air Filter
1. Remove wing bolts (1) from the inspection window at the
bottom rear left on the inside of the operator's cab, then
take out the recirculated air filter.
2. Clean the filter with compressed air. If there is oil on the fil-
ter, or if the filter is extremely dirty, wash it in a neutral
agent. After rinsing it in water, dry it thoroughly before
using it again.
If the clogging of the filter cannot be removed by blowing
with air or washing in water, replace the filter with a new
part every year.
Cleaning Fresh Air Filter
1. Use the starting key to open cover (2) at the rear left of the
operator's cab, then open cover (2) by hand and remove fil-
ter (3) inside the cover.
2. Clean the filter with compressed air. If there is oil on the filter, or if the filter is extremely dirty, wash it in a neu-
tral agent. After rinsing it in water, dry it thoroughly before using it again.
If the clogging of the filter cannot be removed by blowing with air or washing in water, replace the filter with a
new part every year.
3. After cleaning, return filter (3) to its original position and close the cover. Use the starting key to lock the cover.
