Adding Grease Via Grease Fittings Using Grease Gun:
Add grease into the grease tank (6) via the grease fitting lo-
cated on the top of the tank using a electric grease gun.
Note that grease may not be able to added via the grease fit-
ting in cold weather as grease becomes hard. Be sure to fill
the tank full before this happens so that adding grease is not
required while the weather is cold. If adding grease is required
in cold weather, warm the grease cartridge, then add using
the specially designed refilling pump described above. (The
capacity of the tank is approximately 2 liters which could cover
approximately 2000 to 2400 operating hours.)
IMPORTANT: • Check grease tank (6) and add grease as
needed so that the tank does not become
empty. If the electric pump (1) is operated
with the grease tank empty, air will get
into lubrication lines, resulting in insuffi-
cient lubrication.
• Do not remove grease tank upper cover
(13) when greasing. Sand and garbage
may enter into the grease tank (6).
Take special care to keep clean free from
dirt when refilling.
• Be careful not to allow dust to enter
grease tank (6). The electric pump (1) may
be damaged if dust becomes mixed into
the auto lubrication system.
NOTE: The electric pump (1) is equipped with a safety valve.
If the pump delivery pressure exceeds 34 MPa (350
2
kgf/cm , 4980 psi), grease will be discharged from the
safety valve. If this happens, contact your authorized
dealer for inspection.
Also, contact your authorized dealer for any failure of
equipment or lines, or for any inquiries.
