10 SAFETY
7/124 - 10/104, 10/124 - 14/114, 14/84
Keep the towing vehicle or equipment carrier, generator set,
connecting cables, tools and all personnel at least 3 metres from all
power lines and buried power cables, other than those connected to
the generator set.
Attempt repairs only in clean, dry, well lighted and ventilated areas.
Connect the generator set only to loads and/or electrical systems that
are compatible with its electrical characteristics and that are within it’s
rated capacity.
Transport
When loading or transporting machines ensure that the specified lifting
and tie down points are used and cables or chains are within safe
limits.
When loading or transporting machines ensure that the towing vehicle,
its size, weight, towing hitch and electrical supply are all suitable to
provide safe and stable towing at speeds either, up to the legal
maximum for the country in which it is being towed or, as specified for
the machine model if lower than the legal maximum.
Ensure that the maximum trailer weight does not exceed the maximum
gross weight of the machine (by limiting the equipment load), limited by
the capacity of the running gear.
NOTE: Gross mass (on data plate) is for the basic machine and fuel
only, excluding any fitted options, tools, equipment and foreign
materials.
Before towing the machine, ensure that:-
• the tyres and towing hitch are in a serviceable condition.
• the canopy is secure.
• all ancillary equipment is stored in a safe and secure manner.
• the brakes and lights are functioning correctly and meet necessary
road traffic requirements.
• break–away cables/safety chains are connected to the towing
vehicle.
The machine must be towed in a level attitude (the maximum
permissable drawbar angle is between 0° and +5° from horizontal) in
order to maintain correct handling, braking and lighting functions. This
can be achieved by correct selection and adjustment of the vehicle
towing hitch and, on variable height running gear, adjustment of the
drawbar.
To ensure full braking efficiency, the front (towing eye) section must
always be set level.
When adjusting variable height running gear:-
• Ensure front (towing eye) section is set level
• When raising towing eye, set rear joint first, then front joint.
• When lowering towing eye, set front joint first, then rear joint.
After setting, fully tighten each joint by hand and then tighten further to
the next pin. Refit the pin.
When parking always use the handbrake and, if necessary, suitable
wheel chocks.
Make sure wheels, tyres and tow bar connectors are in safe operating
condition and tow bar is properly connected before towing.
Safety chains / connections and their adjustment
The legal requirements for the joint operation of the breakaway cable
and safety chains are as yet unidentified by 71/320/EEC or UK
regulations. Consequently we offer the following advice / instructions.
Where brakes only are fitted:
a) Ensure that the breakaway cable is securely coupled to the
handbrake lever and also to a substantial point on the towing
vehicle.
b) Ensure that the effective cable length is as short as possible, whilst
still allowing enough slackness for the trailer to articulate without the
handbrake being applied.
Where brakes and safety chains are fitted:
a) Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
b) Ensure that the effective chain length is as short as possible whilst
still allowing normal articulation of the trailer and effective operation
of the breakaway cable.
Where safety chains only are fitted:
a) Loop the chains onto the towing vehicle using the towing vehicle
hitch as an anchorage point, or any other point of similar strength.
b) When adjusting the safety chains there should be sufficient free
length in the chains to allow normal articulation, whilst also being
short enough to prevent the towbar from touching the ground in the
event of an accidental separation of the towing vehicle from the
trailer.
