When opening or closing the front window, lower window, or door, always set the lock lever to

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.

jury. Accordingly, wait until they have cooled down before starting the work.
