WARNING
If compressed air is used, there is danger that dirt may fly and cause personal injury.
Always wear protective 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.
CLEAN RECIRC 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.
Replace the filter with a new part every year. If the clog-
ging of the filter cannot be removed by blowing with air or
washing in water, replace the filter immediately.
CLEAN FRESH AIR FILTER
1. Use the starting switch key to open cover (2) at the rear left
of the operator's cab, then open cover (2) by hand and
remove filter (3) inside the cover.
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.
Replace the filter with a new part every year. If the clog-
ging of the filter cannot be removed by blowing with air or
washing in water, replace the filter immediately.
3. After cleaning, return filter (3) to its original position and
close the cover. Use the starting switch key to lock the
cover. Do not forget to remove the starting switch key.
