Model MA TOW Tractor. Manual - part 10

Chapter 1: General Information and Operating Instructions   June 1997           Section 1-2                     p. 7

(c)

Start as slowly as possible to allow any ‘slack’ in towing arrangements to be taken
up.

(d)

Travel at a speed consistent with road and load conditions.

(e)

Slow down and sound the horn when approaching corners and junctions.

(f)

Take all corners wide, especially when towing two wheel steer trailers.

(g)

Always be alert.  Watch out for pedestrian and never drive too close behind other
vehicles.

(h)

Do not carry unauthorized passengers.

(i)

If your trip involves crossing road bridge plates, ensure they are secure and are
strong enough to withstand the combined weight of the tractor and driver, or trailer
and load.

(j)

When approaching the destination, reduce speed sufficiently far away to ensure a
slow, rolling halt.  A sudden halt could cause a load displacement.

(k)

Ensure the trailer’s parking brake is applied by immediately raising drawbar vertically
after disconnecting the trailer coupling.  If no parking brake is fitted, securely chock
the road wheels before disconnecting coupling.

3.

Preventative Maintenance

Maintaining the tractor may, or may not be your responsibility, depending on company
policy.  In either case, maintenance participation, by you (the operator) is advantageous.  It
will enable you to identify the tractor’s components and understand their function so well
that you will be able to report immediately on any mechanical irregularities.

CAUTION: DO NOT ATTEMPT TO CARRY OUR REPAIRS.  LEAVE THIS TO THE
QUALIFIED MAINTENANCE MECHANIC.  REPORT A FAULTY TRACTOR AND DO
NOT USE UNTIL REPAIRED.

Routine maintenance is essential if your tractor is to be an efficient materials handling unit.
Lack of maintenance will result in costly repairs - loss through downtime - and interruptions
in plant operation.
