MAINTENANCE PROCEDURE
METHOD FOR CHECKING STOPPER CLEARANCE IN OPENING FRONT DOOR
IS UP
•
When opening or closing the front window, lower window, or door, always set the lock lever to
LOCK position.
If the lock lever is at FREE position and the control lever or control switch is touched by mistake, It
is dangerous and may cause serious personal injury or death.
•
When opening or closing the front window, stop the machine on a level ground, lower the work
equipment to the ground, stop the engine, then perform the operation.
•
When opening the front window, hold the handle securely with both hands, pull up, and do not let
go until the lock catch is locked.
•
When closing the front window, the window will move quicker under its own weight. Hold the han-
dles securely with both hands when closing it.
If the front window has backlash when it is pulled up, perform the following.
Check if there is clearance (a) between rubber stopper (1) and
plastic guide (2).
Rubber stopper (1) may be worn partially, but it does not affect
the function as long as there is no backlash or clearance.
If there is any clearance, consult your Komatsu distributor.
METHOD FOR WASHING WASHABLE FLOOR
On the washable cab floor, it is possible to flush out the dirt directly with water.
Select a firm flat place.
When positioning the machine at an angle, use strong blocks to stabilize the base of the machine and
be extremely careful when performing the work.
If the control lever is touched by accident, the machine may move suddenly, and this may lead to seri-
ous personal injury or death. Always set the lock lever securely to LOCK position (L) before leaving the
operator's seat.
The cab must be tilted towards the left front side.
