CHECKING, CLEANING AND LUBRICATING THE GUIDE OF THE CAB SLIDING DOOR 4
Checking the cartridge
When opening or closing the sliding door, this may not slide
smoothly due to the presence of dirt in the sliding guide. In this
case, thoroughly clean the guide (1) and the roller (2), and
lubricate the three points indicated in the figure.
Cleaning
1. Open and close the door more than once and remove the
dirt from the guide (1) using a brush.
2. Using a cloth, remove any further residue from the guide
(1).
Lubrication
NOTICE
Do not use high-viscosity oil for lubrication. Use only
grease.
1. Spray the lubricant on the guide (1) and on the roller (2)
uniformly.
2. After lubrication, slide the door and make sure that it can
be easily opened and closed. If it is still difficult to move the
door, contact your Komatsu distributor for the necessary
repairs.
