Maintenance (continued)

Tank

DANGER
!
Never attempt to repair or modi-
fy a tank! Welding, drilling or
any other modification will
weaken the tank resulting in
damage from rupture or explo-
sion. Always replace worn,
cracked or damaged tanks.
NOTICE
Drain liquid from tank daily.
The tank should be carefully inspected at
a minimum of once a year. Look for
cracks forming near the welds. If a crack
is detected, remove pressure from tank
immediately and replace.

Filter Removal, Inspection and Replacement

To change a filter, pull off the filter housing
cover. If filter element is dirty, replace ele-
ment or entire filter.

Drive Belt

Belt stretch is a result of normal use.
When properly adjusted, the belt deflects
about 1/2" with five pounds of pressure
applied midway between the engine pul-
ley and pump (See Figure 12).
To adjust drive belt tension:
1. Remove belt guard and loosen
engine brace.
2. Loosen the four fasteners holding the
engine to the baseplate.
3. Shift the engine in the proper direc-
tion. The belt must be properly
aligned when adjustment is made.
4. To align belt, lay a straight edge
against the face of the flywheel,
touching the rim at two places (See
Figure 13).
5. Adjust flywheel or engine pulley so
that the belt runs parallel to the
straight edge.
6. Use a gear puller to move the pulley
on the shaft and tighten fasteners.
7. Adjust brace and reinstall.

Storage

1. When not in use, hose and compres-
sor should be stored in a cool, dry
place.
2. Tanks should be drained of moisture.
Hose should be disconnected and
hung with open ends down to allow
any moisture to drain.
