8-6. MAINTENANCE-FREE BATTERY CHARG- ING

WARNING: CHARGING A FROZEN BAT- TERY can cause the battery to explode and result in serious personal injury or damage to equipment.

•Allow battery to warm up to 60° F (16°C) be- fore charging if battery is frozen.

BATTERY ACID can burn eyes and skin and destroy clothing and other materials; BAT- TERY GASES can explode and shatter bat- tery.

•Wear a face shield, proper protective cloth- ing, and remove all metal jewelry.

•Do not spill or splash battery fluid.

•Do not apply pressure to walls of filled bat- tery—use battery carrier or place hands on opposite corners when lifting battery.

•Keep sparks, flames, cigarettes, and other ig- nition sources away from batteries.

•Use enough ventilation to keep battery gases from building up during and for several hours after battery charging.

•Do not touch or move connections on battery while battery charger is on.

•Turn battery charger off before making con- nections to battery.

•Do not lean over battery when charging.

•Be sure battery charger connections to bat- tery are clean and tight.

•Keep vent caps in place and cover top of bat- tery with damp cloth.

•Be sure battery charger output matches bat- tery voltage.

•Turn the battery charger off before discon- necting the charger from the battery.

1.Remove battery from unit, and place on a level worktable or other suitable surface.

2.If battery has removable vent caps, check the condition of the electrolyte as follows:

a.Check electrolyte temperature in one of the

center cells with a battery thermometer. For each 10°F (6°C) increment above 80°F (27°C), a correction factor of 0.004 specific gravity

must be added to the specific gravity reading taken in Step 2b. For each 10°F (6°C) incre- ment below 80°F (27°C), 0.004 must be sub- tracted from the reading taken in Step 2b.

b.Check the specific gravity of each cell with a hy- drometer. (Draw in and expel the electrolyte two or three times from the first cell to be tested to adjust the temperature of the hydrometer to that of the electrolyte.)

c.If a corrected specific gravity reading of 1.225 at 80°F (27°C) is not obtained, replace the vent caps and recharge the battery following the bat- tery charger manufacturer’s instructions.

3.If the battery does not have removable vent caps, check the condition of the battery as follows:

a.Check the stabilized open−circuit voltage of the battery. For a 12 volt battery, any reading below

12.4volts indicates the battery needs charging. Disconnect both battery cables from the bat- tery, and allow battery voltage to stabilize for several hours.

b.If the stabilized open−circuit voltage is below

12.4volts, charge the battery following the bat- tery charger manufacturer’s instructions.

4.Remove damp cloth from battery.

5.Reinstall battery in unit.

6.Replace battery holddown, and tighten securely. Do not overtighten.

7.Connect positive (+) battery cable to positive (+) battery terminal.

8.Connect negative (−) battery cable to negative

(−)battery terminal.

8-7. GOVERNOR

The governor has been set at the factory and should not require further adjustment.

8-8. ENGINE SPEED ADJUSTMENTS (Figure 8-2)

WARNING: ELECTRIC SHOCK can kill.

• Do not touch live electrical parts.

• Stop engine, and disconnect negative (−) battery cable from battery before inspecting, maintaining, or servicing.

MOVING PARTS can cause serious injury.

• Keep away from moving parts such as fans, belts, and rotors.

HOT ENGINE PARTS can cause severe burns.

•Wear protective gloves and clothing when working on a hot engine.

Maintenance to be performed only by qualified persons.

The engine speeds have been factory adjusted and should not require frequent readjustment. After tuning the engine, check the speeds with a tachometer. With no load applied, the weld/power speed should be 1860 rpm. If necessary, adjust the speeds as follows:

1.Open and secure right rear side door.

2.Loosen nut on end of engine speed adjusting screw (see Figure 8-2).

3.Start the engine as instructed in Section 7-6.

4.Adjust the weld/power speed as follows:

IMPORTANT: All directions, such as clockwise and counterclockwise, are with respect to the operator fac- ing the rear panel of the unit.

a.To increase weld/power speed, rotate the en- gine speed adjustment screw clockwise.

b.To decrease weld/power speed, rotate the en- gine adjustment screw counterclockwise.
