• Malfunction of the air starting system
When opening the drain valve, wear protective
gloves, a protective face shield, protective cloth-
ing, and protective shoes. Pressurized air could
cause debris to be blown and result in personal
injury.
1. Open the drain valve that is on the bottom of the
air tank. Allow the moisture and sediment to drain.
2. Close the drain valve.
3. Check the air supply pressure. The air starting
motor requires a minimum of 620 kPa (90 psi) of
air pressure to operate properly. The maximum air
pressure must not exceed 1550 kPa (225 psi).
The normal air pressure will be 758 to 965 kPa
(110 to 140 psi).
Battery - Recycle
Always recycle a battery. Never discard a battery.
Return used batteries to one of the following
locations:
• A battery supplier
• An authorized battery collection facility
• A recycling facility
Battery - Replace
Batteries give off combustible gases which can
explode. A spark can cause the combustible
gases to ignite. This can result in severe personal
injury or death.
Ensure proper ventilation for batteries that are in
an enclosure. Follow the proper procedures in or-
der to help prevent electrical arcs and/or sparks
near batteries. Do not smoke when batteries are
serviced.
The battery cables or the batteries should not be
removed with the battery cover in place. The bat-
tery cover should be removed before any servic-
ing is attempted.
Removing the battery cables or the batteries with
the cover in place may cause a battery explosion
resulting in personal injury.
1. Switch the engine to the OFF position. Remove all
electrical loads.
2. Turn off any battery chargers. Disconnect any
battery chargers.
3. The NEGATIVE "-" cable connects the NEGATIVE
"-" battery terminal to the NEGATIVE "-" terminal
on the starter motor. Disconnect the cable from the
NEGATIVE "-" battery terminal.
4. The POSITIVE "+" cable connects the POSITIVE
"+" battery terminal to the POSITIVE "+" terminal
i08397621
on the starting motor. Disconnect the cable from
the POSITIVE "+" battery terminal.
Note: Always recycle a battery. Never discard a
battery. Return used batteries to an appropriate
recycling facility.
5. Remove the used battery.
6. Install the new battery.
Note: Before the cables are connected, ensure that
the engine start switch is OFF.
7. Connect the cable from the starting motor to the
i01878164
POSITIVE "+" battery terminal.
8. Connect the cable from the NEGATIVE "-" terminal
on the starter motor to the NEGATIVE "-" battery
terminal.
Battery Electrolyte Level -
Check
When the engine is not run for long periods of time or
when the engine is run for short periods, the batteries
may not fully recharge. Ensure a full charge in order
to help prevent the battery from freezing. If batteries
are correctly charged, the ammeter reading should
be very near zero, when the engine is in operation.
