5.0 SERVICING YOUR VEHICLE
5.1 MAINTENANCE GUIDELINES
To ensure that the vehicle is kept in a safe and correct operating condition, it must be inspected and maintained on a
regular basis. Proper lubrication, electrical control adjustments, safety feature checks, etc. performed at
recommended intervals will help prevent damage or failure of the unit while providing optimum performance.
No modifications or additions, which affect the mechanical or electrical integrity and the safe operation of
the vehicle shall be made without the written approval of the manufacturer.
If such modifications are approved, the capacity, operation, and maintenance instruction markings shall
be changed accordingly.
In no case shall the safety factors be reduced below those specified in this manual or the manufacturers
design factors, whichever is greater.
Follow the guidelines below to assure proper maintenance.
Before starting any repairs or maintenance, immobilize the vehicle by turning the power keyswitch off, removing
the key and setting the park brake.
Disconnect both of the main battery pack leads before working on or disconnecting any electrical component or
wire.
Block the chassis with jack stands before working under a raised vehicle.
Before starting the vehicle, follow the recommended safety procedures in Chapter 2, (SAFETY).
Do not use flammable fluids for cleaning parts.
Work in a properly ventilated work area.
Regularly inspect and maintain in safe working condition the brakes, steering mechanisms, speed and
directional control mechanisms, warning devices, guards and safety devices.
Keep the vehicle in a clean condition to minimize fire hazards and facilitate detection of loose or defective parts.
5.2 HYDRAULIC BRAKE SYSTEM
These vehicles are equipped with two rear wheel hydraulic brakes as standard or optional four wheel hydraulic
brakes. Monthly, with the vehicle stationary, depress the brake pedal. Pedal should not exhibit excessive travel or feel
spongy or soft.
A hand operated (mechanical) parking brake is used on these vehicles. Monthly check the parking brake operation.
Parking brake hand lever should travel no more than 3-1/2” upward when engaged. Check that ratchet mechanism
automatically holds parking brake handle in the up position. Make sure the release button on the handle frees the
parking brake lever and that the lever returns to full down (released) position.
If any brake problems are noted or suspected do not use the vehicle. Contact your Columbia Dealer for
qualified service assistance.
5.3 BRAKE FLUID MAINTENANCE
Check the brake fluid in the master cylinder periodically (under normal conditions, every 3 months). Use DOT 3 Motor
Vehicle Brake fluid. Maintain fluid level within 1/4" of master cylinder filler opening.
5.4 TIRE CARE
Improper inflation will shorten the life of your tires and will adversely affect performance. For proper tire inflation refer
to manufacturer’s recommendation imprinted on tire sidewall.
NOTICE: Replacement tires must be the same size as original equipment. Increased tire load ratings are
permissible but tire rating does not increase the rated load carrying capacity of the vehicle.
