Section 3 – Maintenance
Batteries in a low state of charge will freeze at higher
temperatures than fully charged batteries. Do not
attempt to charge a battery that is frozen or if battery
case is excessively bulged. Properly dispose of battery,
because frozen batteries can explode.
3. Freezing points of batteries at different specific gravities
is shown below.
O O
NOTICE: Specific gravity readings are at 80
0
F. Values
need adjustment for electrolyte temperature. Reduce
.004 for every 10
0
F below 80
0
F. Increase by that amount
for every 10
0
F above.
4. For vehicles with a single point watering system, check
water levels quarterly per
Section 9.
5. Charge batteries fully then check fluid levels. Store
batteries in as cool place as possible.
6. Dis connect battery negative terminal.
7. Wash off any corrosion around the terminals with a
solution of baking soda and water. Do not allow this
solution to enter batteries.
8. Do not engage parking brake. Block wheels to prevent
movement.
RETURNING VEHICLE TO SERVICE:
1. Reconnect battery negative terminal.
2. Fully recharge batteries and check fluid levels.
For vehicles with a single point watering system: After the
batteries have been fully charged, connect the system to
its water supply for 3-5 seconds then disconnect
regardless of whether or not the batteries are completely
full. Return the vehicle to its regular service. Place the
vehicle back into its regular watering schedule (waiting at
least 1 week until next watering)
.3. Check tire pressure and readjust if necessary.
4. Perform initial maintenance per periodic maintenance in the
beginning of this section.
6. Return the vehicle to its regular service.
TRANSPORTING A VEHICLE
NOTICE: Never tow a vehicle behind an auto or truck
unless on an approved trailer.
When trailering a vehicle over long distances or on the highway
observe the following:
1. Use trailers specifically designed to carry your Columbia
ParCar vehicle that meets all federal, state and local
requirements.
2. Secure vehicle to the trailer following trail
er manufacturer’s
instruction.
3. The key should be removed from the vehicle, the parking
brake firmly locked, and the wheels blocked.
4. On vehicles equipped with high or wide additions or
accessories be certain they are secured properly to
prevent loss or damage.
Use care when transporting on windy days. Example: A
60 MPH speed into a 40 MPH head wind is equal to
traveling at 100 MPH. Industrial vehicles are not rated
to withstand this level of stress and parts could be
blown off, causing accident or injury.
