11 PRE-OPERATION CHECK
1. Remove the vent plugs.
2. Fill cells up to the upper level with electrolyte.
[Specific gravity of sulfuric acid 1.270 to 1.290 (at
20 C=68 F)]
3. Allow the battery to sit for about one hour after filling.
4. If the electrolyte level is dropped, refill with electrolyte
up to the upper level.
5. Replace the vent plugs.
6. Charge the battery at the normal charging rate of 6.0
amperes.
7. Wash off any electrolyte which may have spilled.
A
The duration of dry charged efficiency, will decrease in
proportion to the period of time elapsed after shipment
and during storage. To obtain the longest service life
of the battery, it is necessary for the battery to be
charged for a sufficient period of time. Continue to
charge until all cells are gassing freely, and the
voltage and specific gravity reading in all cells remain
constant for 3 or more successive readings taken at
30 minute intervals.
A
When the battery has been charged fully, the specific
gravity of electrolyte should be 1.270 to 1.290 (at 20 C
=68 F).
B
Engine Oil
The generator has been shipped without engine oil.
Fill with oil to the correct level before attempting to
start the engine.
1. Place the machine on a level surface.
2. Remove the oil cap.
3. Add engine oil of grade CF or higher, up to the upper
mark on the oil level gauge.
A
See "ENGINE OIL" in "PERIODIC SERVICE" section
for engine oil capacity and checking engine oil level.
B
Coolant
To avoid personal injury:
A
Place the machine on a level surface.
A
DO NOT remove the radiator cap
while coolant is hot. When cool,
rotate the radiator cap slowly to the
first stop to allow excess pressure to
escape. Then remove cap
completely.
1. Remove the radiator cap and fill with specified coolant
until the coolant level is just below the port.
2. Fill with coolant to the “FULL” mark on the recovery
tank.
3. Securely tighten radiator cap and recovery tank cap.
A
See "RADIATOR" in "PERIODIC SERVICE" section
for changing coolant.
B
Opening and Closing of the Fuel Tank Cap
1. Open the tank cap cover, insert the tank cap cover key
and turn clockwise. Then turn the tank cap
counterclockwise to open.
2. To close the tank cap, turn clockwise and the tank cap
cover key in the opposite direction. Then close the
tank cap cover.
(1) Vent plug opening
(2) Electrolyte level indication tube
(3) Indicated level (A) Upper level
(B) Lower level
There are three types of key. Select the key as necessary.
(1) Key
(2) Fuel tank cap
(3) Tank cap cover
