SQUEEGEE BLADE ADJUSTMENT

For optimum squeegee blade performance, the
squeegee assembly casters must be adjusted to a
specified height as described below.
1. To check the squeegee assembly for proper
adjustment, remove the squeegee assembly from
the machine and place it on a level surface.
Measure the distance between the caster and the
surface. It should measure approximately 2 mm
(1/16 in) (Figure 40).
2. To adjust the caster height, loosen the top nut and
remove the plastic bearing cover to access the
adjustment nut. Turn the adjustment nut until
properly adjusted (Figure 40). After adjusting,
tighten the top nut and replace the plastic bearing
cover. Repeat step for the other caster.
3. During machine operation, with the casters
properly adjusted, the squeegee blades should
deflect as shown (Figure 41).

BATTERY MAINTENANCE

WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Check the specific gravity using a hydrometer to
determine the charge level and the condition of the
batteries (Figure 42). If one or more of the battery
cells read lower than the other battery cells (0.050
or more), the cell is damaged, shorted, or is about
to fail. Check the hydrometer readings against the
following chart to determine the remaining battery
charge level.
NOTE: Do not take readings immediately after adding
distilled water. If the water and acid are not thoroughly
mixed, the readings may not be accurate.
SPECIFIC GRAVITY
at 27_C (80_F)

1.223
1.185
1.148
1.110
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C (80_F),
the reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C (43_F) above or below 27_C (80_F).
2. Always follow proper charging instructions
(See CHARGING BATTERIES).
