If the charger is used for stand-by use purposes, it is advised to maintain the charge on the “LOW” position for a float
7.
charge.
For a fast charge time, switch the HIGH/OFF/LOW control panel switch to the “HIGH” position for a bulk charge. If the
8.
engine becomes overloaded on this setting due to a larger current drag from larger battery banks, keep the switch on
“LOW” to slowly increase the battery voltage, before switching back to “HIGH”.
Before removing the battery cable clamps from the battery, switch the HI/OFF/LOW control panel switch to “OFF”.
9.
Always disconnect the battery cable from the battery when the engine is not running.
10.
NEVER REVERSE THE LEADS AS THIS MAY CAUSE PERMANENT OR SEVERE DAMAGE TO THE CHARGER AND BATTERIES.
MAINTENANCE
Check fuel and oil levels before starting. Fill engine oil to the top of the filler hole with the engine on a level surface. Use
•
manufacturers recommended type of oil.
Always use clean, fresh unleaded fuel. Some fuels deteriorate over time, causing hard starting. Check fuel and oil levels
•
before starting. Fill engine oil to the top of the filler hole with the engine on a level surface.
If vibration noises increase over time, check for loosened nuts and bolts on the unit.

REFER TO THE ENGINE MANUAL FOR FURTHER ENGINE MAINTENANCE PROCEDURES
NOTE
Always remember, batteries can fail and this battery charger cannot re-charge an unserviceable battery, however the unit
can provide a steady current to operate DC loads even when the batteries cannot store or deliver power.
BATTERY CARE
Running any battery completely flat can and will result in permanent battery failure, or decrease the life of the
•
batteries. Lead acid batteries are best kept clean and dry at a moderate 70ºF/20ºC temperature and fully charged
for best performance. Cranking batteries will recharge quickly due to the internal design while deep cycle batteries
re-charge more slowly.
Batteries can be severely damaged if repeatedly discharged beyond 80% of their rated capacity, whether it is a deep
•
cycle or cranking battery. A fully charged battery (once stabilized) will measure 12.6 volts (approx.) or measure 1.260
specific gravity. A flat battery will measure 11.9 volts (approx.) or measure 1.150 specific gravity.
Whenever handling or working with a lead-acid battery, consult the battery manual or specification sheets for
•
instructions and safety precautions. Lead-acid batteries produce hydrogen-oxygen gases than can be highly
explosive and sulphuric acid can cause severe burns.
