TOWING AND HOISTING
TOWING AND HOISTING
The MONTERO can only be towed from the front with
conventional sling-type equipment and tow chain &th
grab hooks.
If a vehicle is towed from the rear, use a tow dolly.
A lumber spacer (4” x 4” x 55” wood beam) should be
placed forward of under guard and under towing hook/
shipping tie down hook.
Then, attach J-hook to the lower arm.
A safety chain system must be used. This system must be
completely independent of the primary lifting and’ towing
attachment. Care must be taken in the installation of safety
chains to insure they do not cause damage to bumper,
painted surfaces or lights.
Lifting-Ground Clearance
Towed vehicle should be raised until wheels are a minimum
of 10 cm (4 in.) from the ground. Be sure there is
adequate ground clearance at the opposite end of the vehicle,
especially when towing over rough terrain or when crossing
sharp rises such as curbs. If necessary, ground clearance can
be increased by removing the wheels from the lifted end of
the disabled vehicle and carrying the lifted end closer, to the
ground. A 20 cm (8 in.) ground clearance must be maintained
between brake drums and ground.
Front Towing Pickup
The vehicle may be towed on its rear wheels for extended
distances, provided the parking brake is released.
Make certain the transmission remains in “NEUTRAL”.
Safety Precautions
The following precautions should be taken when towing the
vehicle.
1. Remove exhaust tips and any other optional equipment,
that interface with the towing sling. Padding (heavy shop
towel or carpeting) should be placed between the towing
sling cross bar and any painted surfaces, and bumper
surfaces.
2. A safety chain system completely independent of the pri-
mary lifting and towing attachment must be used.
3. Any loose or protruding parts of damaged vehicle such as
hoods, doors, fenders, trim, etc., should be secured prior
to moving the vehicle.
4. Operator should refrain from going under a vehicle unless
the vehicle is adequately supported by safety stands.
5. Never allow passengers to ride in a towed vehicle.
6. State and local rules and regulations must be followed
when towing a vehicle.
