PRECAUTIONS FOR MAINTENANCE

PRECAUTIONS BEFORE STARTING INSPECTION AND MAINTENANCE

DISPLAY WARNING TAG DURING INSPECTION AND MAINTENANCE

During inspection and maintenance, always display the "DAN-
GER! Do NOT operate!" warning tag.
If  there  is  a  "DANGER!  Do  NOT  operate!"  warning  tag  dis-
played,  it  means  that  someone  is  performing  inspection  and
maintenance of the machine. If the warning tag is ignored and
the  machine  is  operated,  the  person  performing  inspection  or
maintenance  may  be  caught  in  the  rotating  parts  or  moving
parts. It is dangerous and may cause serious personal injury or
death. Do not start the engine or touch the levers.
If necessary, put up signs around the machine as well.
Warning tag part No. 09963-A1640
When not using this warning tag, keep it in the toolbox. If there
is  no  toolbox,  keep  it  in  the  pocket  for  Operation  and  Mainte-
nance Manual

KEEP WORK PLACE CLEAN AND TIDY

• Do not leave hammers or other tools lying around in the work place. Wipe up all grease, oil, or other sub-

stances that will cause you to slip. Always keep the work place clean the tidy to enable you to perform oper-
ations safely. If the work place is not kept clean and tidy, there is the danger that you will trip, slip, or fall
over and injure yourself.

• When cleaning the ceiling window which is made of organic glass (polycarbonate), use tap water and avoid

use of organic solvents for cleaning. An organic solvent like benzene, toluene or methanol can invite a
chemical reaction like dissolution and decomposition on the window glass, deteriorating polycarbonate in
use.

SELECT SUITABLE PLACE FOR INSPECTION AND MAINTENANCE

• Stop the machine on a firm, level ground.
• Select a place where there is no hazard of landslides, falling rocks, or flooding.

ONLY AUTHORIZED PERSONNEL

As long as maintenance of the machine is continued, do not allow unauthorized person to come near the work-
place. They might get unexpected personal injury from, for instance, touching machine. Do not allow anyone
except the workers concerned to enter the workplace. If necessary, employ a guard.

APPOINT LEADER WHEN WORKING WITH OTHERS

When repairing the machine or when removing and installing the work equipment, appoint a leader and follow
his/hers instructions during the operation in order to prevent personal injuries caused by being caught or
pinched.

STOP ENGINE BEFORE CARRYING OUT INSPECTION AND MAINTENANCE

If you are caught or pinched between the work equipment during operation, or exposed to high-temperature or
high-pressure liquids, it is dangerous and may cause serious personal injury or death. Always observe the fol-
lowing.
