CARE AND MAINTENANCE
Your Blast is a sophisticated power chair. Like any motorized vehicle, it requires routine maintenance checks. You can perform
some of these checks, but others require assistance from an authorized Pride provider. Preventive maintenance is very
important. If you follow the maintenance checks in this section as scheduled, you can help ensure that your Blast gives you
years of trouble-free operation. If you have any doubt as to your Blasts care or operation, contact your
authorized Pride provider.
Your Blast, like most electrical equipment, is susceptible to damage from the elements. Avoid damp areas of any kind.
WARNING! Direct exposure to water or dampness could cause the power chair to malfunction
electronically and mechanically. Water can cause electrical components to corrode and the chairs frame
to rust.
Should your Blast come in contact with water:
1. Dry your Blast as thoroughly as possible with a dry towel.
2. Allow your Blast to sit in a warm, dry place for 12 hours to allow unseen water to evaporate.
3. Check the joystick operation and the brakes before using your Blast again.
4. If any inconsistencies are found, take your Blast to an authorized Pride provider.
Temperature
Some of the parts of your Blast are susceptible to extreme changes in temperature. Always keep your Blast between the
temperatures of 18° F and 122° F.
n
In extremely cold temperatures the batteries may freeze. The specific temperature at which they freeze depends on a
number of factors, such as battery charge, usage, and composition of the batteries (e.g., sealed lead-acid or gel cell).
n
Temperatures above 122° F may cause your Blast to operate at a reduced speed. This reduced speed is a safety feature
built into the controller that helps prevent damage to the motor and other electrical components. See VIII.
Operation.
General Guidelines
n
Avoid knocking or bumping the controller, especially the joystick.
n
Avoid prolonged exposure of your Blast to extreme conditions, such as heat, cold, or moisture.
n
Keep the controller clean.
n
Check all connectors on the electronics tray to ensure that they are all tight and secured properly.
n
When the battery condition meter is completely lit, the batteries are fully charged, and the controller and the electrical
system are OK.
n
If one red light on the battery condition meter is blinking slowly, the batteries are low and need to be charged, but the
controller and the electrical system are OK.
n
If the battery condition meter is blinking rapidly, the controller has detected a fault in either its own circuits or in your
Blasts circuits. See VIII. Operation.
n
Make sure the drive tires are inflated to
30 35 psi.
WARNING! Make sure your tires are inflated to 30-35 psi. Do not underinflate or overinflate your tires. Low
pressure may result in loss of control, and overinflated tires may burst. Serious personal injury may result.
Overinflating tires can cause them to explode and can result in personal injury.
WARNING! Do not use a high pressure hose to inflate your tires.
