Owner’s Manual for Flameless Air Heater 7
General Information
Driving a vehicle with a trailer in tow is vastly different
than driving the same vehicle without a trailer in tow.
Consider the following:
• It takes longer to get up to speed.
• More room is needed to turn and pass.
• More distance is needed to stop.
• The driver is responsible for keeping the vehicle
and trailer in control
Before towing, verify the following:
1.
The coupling, safety chains, safety brake, tires,
wheels and lights are in working order.
2.
The breakaway battery is fully charged.
3.
Wheel lug nuts are tightened to 85-95 ft-lbs (115-
129 Nm).
4.
Brake controller engages the trailer brakes before
the tow vehicle brakes.
While towing, make regular stops to verify the following:
1.
Coupler is secured to the hitch and locked.
2.
Electrical connections are made.
3.
Appropriate slack in the safety chains.
4.
Appropriate slack in the breakaway switch pull-pin
cable.
5.
Tires are inflated to proper air pressure and no
damage or unusual wear to tread or sidewalls.
6.
Trailer and doors are secured and latched.
Wheel Chock Guidelines
• Select wheel chock according to equipment type
and size
• Always use in pairs and on firm surfaces
• Chock in direction of grade
• Chock both sides of wheel if direction of grade is
unknown
• Use wheel chock only after parking brake is
applied and tested
• Center chocks squarely against tread of each
wheel
• Do not drive over wheel chocks
