WA80M-7, WA100M-7 – VENAM03001
Before executing the inspection and maintenance
Choose a location where there is no risk of landslide, rockfall or
flood.
Before performing inspection and maintenance tasks, park the
machine on solid, level ground. Lower the work unit. If your
machine is equipped with E.C.S.S., you have to switch off the
E.C.S.S.. Switch off the engine and secure the machine.
If the engine has to remain on during maintenance, e.g. during
pressure inspection of the hydraulic system, proceed with
extreme caution. Only perform this work in pairs after defining
unmistakable signals.
One person has to remain on the operator's seat to immediately
shut down the engine when necessary. Only operate the operat-
ing level after consulting the second person.
The person performing the maintenance has to be careful not to
touch or get caught in moving parts.
Ensure steady positioning
When disassembling or assembling the machine for maintenance
or repair, ensure at each stage that the machine is in a steady
position. Failure to comply with this can lead to injury or death.
Guards
The area around the engine contains guards to protect persons
from moving parts. These guards can only be removed by
Komatsu customer service technicians, unless specific instruc-
tions are provided in this manual.
