Battery Maintenance - Generac G0062700 Manual Del Propietário

• Make sure the piston is at top dead center (TDC) of its
compression stroke (both valves closed). To get the
piston at TDC, remove the intake screen at the front of
the engine to gain access to the flywheel nut. Use a
large socket and socket wrench to rotate the nut and
hence the engine in a clockwise direction. While
watching the piston through the spark plug hole. The
piston should move up and down. The piston is at TDC
when it is at its highest point of travel.
To adjust valve clearance (see
• The engine should be cool before adjustment.
• Remove spark plug wires and position wires away from
plugs.
• Remove spark plugs.
• Remove the four screws attaching the valve cover.
Remove and discard gasket.
• Loosen the rocker jam nut (A). Using a 10mm Allen
wrench (530 cc engine) or a 13mm Allen wrench (990
cc engines).
• Turn the pivot ball stud (B) while checking clearance
between the rocker arm (C) and the valve stem (D) with
a feeler gauge. Correct clearance is in the specification
in Section 2— Engine.
NOTE: Hold the rocker arm jam nut in place as the pivot
ball stud is turned.
•
When valve clearance is correct, hold the pivot ball stud
in place with the Allen wrench and tighten the rocker
arm jam nut. Tighten the jam nut to 174 in-lbs (19.68
Nm) torque. After tightening the jam nut, recheck valve
clearance to make sure it did not change.
• Install new valve cover gasket.
•
Install the valve cover. Tighten fasteners in a cross
pattern, torquing to 48 in-lbs (5.4 Nm).
NOTE: Start all four screws before tightening or it will
not be possible to get all the screws in place. Make sure
the valve cover gasket is in place.
• Install spark plugs.
•
Re-attach the spark plug wire to the spark plug.
• Repeat the process for the other cylinder, if necessary.

Battery Maintenance

The battery should be regularly inspected per the
Service Schedule:
1. With the generator shut down, lift the lid and
remove the front panel.
2. Inspect the battery posts and cables for tightness
and corrosion. Tighten and clean as necessary.
3. Check the battery fluid level of unsealed batteries,
and, if necessary, fill with distilled water only. DO
NOT use tap water. Also, have the dealer or a
Owner's Manual for 50 Hz Air-Cooled Generators
Figure 4-4):
qualified Service Technician check the state of
charge and condition.
WARNING
Explosion. Do not dispose of batteries in a fire.
Batteries are explosive. Electrolyte solution can cause
burns and blindness. If electrolyte contacts skin or eyes,
flush with water and seek immediate medical attention.
WARNING
WARNING
Electrical shock. Disconnect battery ground
terminal before working on battery or battery
wires. Failure to do so could result in death
or serious injury.
WARNING
WARNING
Environmental Hazard. Always recycle batteries at an
official recycling center in accordance with all local
laws and regulations. Failure to do so could result in
environmental damage, death or serious injury.
Strictly observe the following precautions when working
on batteries:
• Remove the 7.5 Amp fuse from the generator control
panel.
•
Remove all jewelry—watches, rings, metal objects, etc.
• Use tools with insulated handles.
•
Wear rubber gloves and boots.
• Do not place tools or metallic objects on top of the battery.
• Disconnect the charging source prior to connecting or
disconnecting battery terminals.
•
Wear full eye protection and protective clothing.
• Where electrolyte contacts the skin, wash it off
immediately with water.
• Where electrolyte contacts the eyes, flush thoroughly
and immediately with water and seek medical attention.
• Wash down spilled electrolyte with an aid neutralizing
agent. A common practice is to use a solution of one
pound (500 grams) bicarbonate of soda to one gallon
(four liters) of water. The bicarbonate of soda solution is
