requires only periodic canister filter
servicing.
Every 12 months
or
12,000
miles, whichever occurs first, (more
often under dusty conditions) the
filter in the base of the canister
must be replaced and the canister
inspected.
Drive
Beltl
Every 6,000 miles or 4
months-
inspect drive belts for wear, fray-
ing, cracking, and tension. Belts
which are in poor condition should
be replaced immediately.
Check tension by applying
mod-
erate thumb pressure midway be-
tween
pUlleys.
If
the center-to-
center distance between pulleys
is
13
to
16 inches, the belt should
deflect
lh inch.
If
the center-to-
center distance
is
7 to 10 inches,
the belt should deflect
1;4
inch.
Loose belts should be retensioned
to give the correct deflection.
