MAINTENANCE
Greasing Method
IMPORTANT: When lubricating a closed space with
grease, the motor rotation becomes slow as soon as
grease is sufficiently filled in the lubrication space
End greasing by releasing switch (1). If greasing is
continued further, burning of the motor may result.
1. Drive the motor by pulling switch (1). Grease is
discharged from the tip of nozzle (3).
f
NOTE: When the grease gun is first used, it takes some time
before discharging grease until air is bled from the motor
assembly.
2. After cleanly wiping the tips of the grease fitting through
which grease is added and gun nozzle (3), press the tip
of nozzle (3) to chuck the grease fitting.
3. Pull switch (1) to discharge grease.
When grease is normally added, old grease is discharged
through the clearance around the grease fitting.
4. After completing greasing, allow the inner pressure to
release from the grease fitting by tilting nozzle (3) before
disconnecting the tip of nozzle (3) from the grease
fitting.
Certain amount of grease escapes at this time.
f
NOTE:
 If the motor rotation becomes very slow or stops during
greasing, immediately release switch (1).
 The electric grease gun is a high speed type so that slight
amount of grease may escape from the plunger. This is not
a fault.
