MAINTAINING THE BATTERY AND
BATTERY CONNECTIONS
WARNING
Arcing at battery terminals or light
switch or other equipment or flames and sparks
can ignite battery gas causing severe personal
injury—Ventilate battery area before working on
or near battery—Wear safety glasses—Do not
smoke—Switch trouble light ON / OFF away
from battery—Do not disconnect battery cables
while genset is running or vehicle battery charg-
ing system is on—Always disconnect nega-
tive (−) cable first and reconnect it last.
Refer to Table 3-1 for scheduled battery mainte-
nance, and follow the battery manufacturer’s in-
structions. Have the battery charging system ser-
viced if DC system voltage is consistently low or
high. Always:
1. Keep the battery case and terminals clean and
dry and the terminals tight.
2. Remove battery cables with a battery terminal
puller.
3. Make sure which terminal is positive (+) and
which is negative (−) before making battery
connections, always removing the negative (−)
cable first and reconnecting it last to reduce
arcing.
REPLACING THE AIR FILTER ELEMENT
Refer to Table 3-1 for scheduled air filter element re-
placement. In dusty environments the filter element
should be inspected and changed more frequently.
To change the filter element (Figure 3-3):
1. Remove the air filter housing cover and filter
element cover plate, which are secured by sep-
arate wing nuts, and remove the filter element.
2. Reassemble the air filter with a new filter ele-
ment. Make sure the filter element is centered
over the carburetor air inlet. Do not tighten the
wing nuts too tightly. Excessive tightening can
distort the filter element and cause air leaks
around the element.
