WEEKLY MAINTENANCE
1. Use a hydrometer to check the condition of each
battery cell.
2. Check battery cable clamps. Ensure clamps are
tight on battery terminals.
3. Clean tops of batteries with a wet cloth and a
solution of water and baking soda. Wipe battery
tops dry after cleaning.
4. Check pad lock for looseness or damage.
5. Check filter and filter seals. Airflow should be
unobstructed through filter.
6. Ensure that the pivot points and casters are
properly lubricated.
7. Tighten any loose screws or nuts.
4 TO 6 MONTH MAINTENANCE

SHUNT ADJUSTMENT
This pad pressure meter adjustment is factory set.
Over the course of time it may become necessary to
adjust this setting using the slotted connection on
the shunt.
SHUNT ADJUSTMENT (Cont.)
Check the amp range when nuisance tripping of the
circuit breaker indicates that the shunt may be out of
adjustment.
1. Connect a DC ampere meter to the positive
battery lead. Running the machine with a pad,
lower the pad to the floor until it is operating at
55-60 amps.
2. Moving the wire in the slot, adjust the pad
pressure meter until the needle sets at the line
between the green and red areas.
3. Check the other points indicated in the diagram
above. The high end should trip the circuit
breaker. Replace the pad pressure meter if the
approximate amp ranges shown cannot be set.
SHAFT ADJUSTMENT
If shaft is replaced make sure it is adjusted
correctly upon installation.
