PUSHING, TOWING, AND TRANSPORTING
THE MACHINE
PUSHING OR TOWING THE MACHINE
If the machine becomes disabled, it can be
pushed from the front or rear, but only tow it from
the front.
Only push or tow the machine for a very short
distance and do not exceed 3.2 kp/h. It is NOT
intended to be pushed or towed for a long
distance or at a high speed.
ATTENTION! Do not push or tow
machine for a long distance or damage
may occur to the propelling system.
TRANSPORTING THE MACHINE
1. Position the front of the machine at the
loading edge of the truck or trailer.
FOR SAFETY: Use a truck or trailer that
will support the weight of the machine.
NOTE: Empty the recovery and solution tanks
before transporting the machine.
2. If the loading surface is not horizontal or is
higher than 380 mm from the ground, use a
winch to load machine.
If the loading surface is horizontal AND is
380 mm or less from the ground, the
machine may be driven onto the truck or
trailer.
3. To winch the machine onto the truck or
trailer, attach the winching chains to the front
tie down locations. The front tie-down
locations are on the front sides of the
machine. Make sure the machine is
centered.
FOR SAFETY: When loading machine
onto truck or trailer, use winch. Do not
drive the machine onto the truck or
trailer unless the loading surface is
horizontal AND is 380 mm or less from
the ground.

GENERAL INFORMATION
1-12 7100 330695 (10−00)
4. Position the machine onto the truck or trailer
as far as possible. If the machine starts to
veer off the centerline of the truck or trailer,
stop and turn the steering wheel to center
the machine.
5. Set the parking brake, lower the scrub head
and block the machine tires. Tie down the
machine to the truck or trailer before
transporting.
The front tie-down locations are on the front
jack supports.
The rear tie-down locations are on the rear
corners of the machine.
6. If the loading surface is not horizontal or is
higher than 380 mm from the ground, use a
winch to unload machine.
If the loading surface is horizontal AND is
380 mm or less from the ground, the
machine may be driven off the truck or
trailer.
FOR SAFETY: When unloading machine
off truck or trailer, use winch. Do not
drive the machine off the truck or trailer
unless the loading surface is horizontal
AND 380 mm or less from the ground.

MACHINE JACKING
Jack up the machine from underneath all four
corners of the machine. Use a piece of wood
between the jack and frame to distribute the
machine weight load.
Always stop the machine on a flat level surface
and block the tires before jacking the machine up.
FOR SAFETY: When servicing machine,
block machine tires before jacking
machine up.
FOR SAFETY: When servicing machine,
jack machine up at designated locations
only. Block machine up with jack
stands.
Jack up the rear of the machine from underneath
the rear corners. Use a piece of wood between
the jack and the frame to distribute the machine
weight load.
FOR SAFETY: When servicing machine,
block machine tires before jacking
machine up.
FOR SAFETY: When servicing machine,
jack machine up at designated locations
only. Block machine up with jack
stands.

HARDWARE INFORMATION
The following charts state standard plated
hardware tightening ranges for normal assembly
applications. Decrease the specified torque by
20% when using a thread lubricant. Do not
substitute lower grade hardware for higher grade
hardware. If higher grade hardware than specified
is substituted, tighten only to the specified
hardware torque value to avoid damaging the
threads of the part being threaded into, as when
threading into speed nuts or weldments.
