GENERAL GUIDELINES FOR WELDING
Welding work must be performed by a certified welder at a facility where welding devices are properly
equipped. Damage of electric parts, poisoning gas from paint due to heat of welding or a fire may
occur.
Basic Precautions for Welding
・ Turn the starter switch to the "OFF" position.
・ Disconnect the cable at the negative (-) terminal of the battery to cut off the current.
・ Attach welder ground cable within 1 m {3.3 ft.} from the part to be welded. If the welder ground
cable is attached to the area near electric parts/connectors, these electric parts/connectors may be
damaged.
・ Attach the welder ground cable directly to the area near the part to be welded and on the same
parent material.
・ Make sure that neither the bearing nor seal is positioned between the welder ground cable and the
part to be welded.
・ Do not attach the welder ground cable near the attachment pin or cylinder. It will damage plating.
・ Remove paint from any surface to be welded to avoid generating poisonous gas.
・ Always wear protective gears appropriate for welding.
・ Perform work in a well-ventilated areas.
・ Clear flammable materials and provide a fire extinguisher in preparation for a fire.
SUPPORT WHEN JACK-UP
Accident may occur without support. When lifting
up the machine for inspection of the
undercarriage, operate the boom and arm to form
an angle of 90 to 110 degrees between them,
and lower the bucket to let its bottom touch the
ground to lift the machine body up, and support
the machine with safety strut (1) and safety block
(2).

USE CAUTION WHEN ADJUSTING THE TRACK TENSION
Grease cylinder is under extreme high pressure.
It is dangerous to loosen the grease nipple
rapidly because grease will splash. Loosen the
grease fitting within one turn while relieving
pressure gradually.
Keep a face, hands and legs away from the
grease nipple.
For adjusting track shoe tension, see "CHECKING
AND MAINTAINING TRACK SHOE TENSION" in
Chapter 4.
