Metro Power III Owner’s Manual GF0600059RevB06, November 2006 29
VIII MaINteNaNCe
We urge you to protect your power drive wheelchair investment by keeping your Metro Power III in
top condition. Periodic inspection, adjustment, and replacement of worn parts will provide years of
superb performance. When a component or part does not function properly, a potentially hazardous
condition can result. Only excellent condition is acceptable where safety is concerned.
Note: We recommend that you have a qualified Graham-Field dealer perform the 6 month mainte-
nance checks, because some special tools are required. Because the dealer has years of experience
and training with power wheelchairs, the dealer may find and correct a problem that might
otherwise go undetected and eventually cause more serious problems.

You can do many of the scheduled maintenance tasks yourself, if you have mechanical ability and
a few basic tools. Refer to the maintenance schedule below for the recommended regularity of each
procedure. If any maintenance procedure is not clear to you, ask your Graham-Field dealer for as-
sistance.
