Safety
The Safety section lists basic safety precautions. In
addition, this section identifies the text and locations
of the warning signs and labels used on the machine.
Read and understand the basic precautions listed in
the Safety section before operating or performing any
lubrication, maintenance or repair on this machine.
Operation
The Operation information is a reference for the new
operator and a refresher for the experienced one. This
section includes a discussion of gauges, switches,
machine controls, attachment controls, transportation,
and towing information.
Photographs and illustrations guide the operator
through the correct procedures for checking, starting,
operating and stopping the machine.
Maintenance
The maintenance information is a guide to equipment
care for Army operators. The illustrated, step-by-step
instructions are grouped by servicing intervals. Items
without specific intervals are listed under the When
Required topics. Items in the Maintenance Intervals
chart (refer to “Maintenance Section, Maintenance
Intervals” in this manual) are referenced to detailed
instructions that follow.
Maintenance Interval Schedule
Use the service hour meter to determine the servicing
intervals. Calendar intervals shown (daily, weekly,
monthly, etc.) can be used instead of the service hour
meter intervals, if they provide more convenient
servicing schedules and approximate the indicated
service hour meter reading. Recommended service
should always be performed at the interval that occurs
first.
Under extremely severe, dusty or wet operating
conditions, more frequent lubrication than is specified
in the Maintenance Intervals chart might be necessary.
Perform service on items at multiples of the original
requirement. For example, at Every 50 Service Hours
or Weekly, also service those items listed under Every
10 Service Hours or Daily.
