NFORMATION
Proper machine operation depends upon a properly maintained machine. This section provides a list
of items to be checked, inspected or changed periodically.
NOTE:
Section 4 includes machine lubrication and maintenance instruction but excludes engine
lubrication and maintenance instruction. Refer to Section 5 for lubrication and maintenance
instructions for the Cummins engine, and Section 6 for lubrication and maintenance instructions
for the CAT engine.
When performing maintenance, always park motor grader on level ground with the moldboard on the
ground and implements pinned in place or lowered to the ground.
Dispose of all used fluids and filters according to federal, state and local regulations.
Welding Precautions
Proper welding procedures are necessary in order to avoid damage to the electronic controls and to
the bearings. When possible, remove the component that must be welded from the machine or the
engine and then weld the component. If you must weld near an electronic control on the machine or
the engine, temporarily remove the electronic control in order to prevent heat related damage. The
following steps should be followed in order to weld on an machine or an engine with electronic
controls.
1. Turn OFF the engine. Place the engine start switch in the OFF position.
2. Turn the battery disconnect switch to the OFF position.
NOTICE:
DO NOT use electrical components (ECM or ECM sensors) or electronic component
grounding points for grounding the welder.
3. Clamp the ground cable from the welder to the component that will be welded. Place the clamp as
close as possible to the weld. Make sure that the electrical path from the ground cable to the
component does not go through any bearing. Use this procedure in order to reduce the possibility
of damage to the following components:
• Bearings of the drive train
• Hydraulic components
• Electrical components
• Other components of the machine
4. Never allow welding cables to lay on, near, or across any electrical wiring or electronic component
while welding.
5. Protect any wiring harnesses and hydraulic hoses from the debris and weld splatter which is
created from welding.
6. Always have a fire extinguisher available when welding.
Never grease, service or adjust machine with engine running, except as specified
in this manual or the service and repair manual.
