AIR AND LUBE REQUIREMENTS (cont)
•
Filtered and oiled air will allow the pump to operate more efficiently
and yield a longer life to operating parts and mechanisms.
•
Lack of or an excessive amount of lubrication will affect the perfor-
mance and life of this pump. Use only recommended lubricants.
•
DAILY Fill air line lubricator with a good grade of S.A.E. NO. 90W
non-detergent gear oil, adjust to 1 to 2 drops per minute.
•
If pump is to be inoperative for more than a few hours at a time, dis-
connect air supply and relieve all pressure from the system.
It is recommended that an oiler be installed in the air line as close as pos-
sible to the pump. This increases the service life of the pump byreducing
wear of the air motor’s internal parts.
TROUBLE-SHOOTING
Should pump operate, but dispense little or no material, check for:
•
Inadequate supply of material or possible malfunctioning of 77006
Foot Valve which would prevent material from feeding into suction
tube.
•
Dirt or foreign matter in 77006 Foot Valve or other cause which may
be preventing it from closing on downstroke of piston.
If unit should fail to operate, the following procedure will be helpful in de-
termining the cause:
•
Checkair pressure at pump to insure air line is not obstructed and air
is being supplied to pump.
•
If insufficient air is not the trouble, disconnect air supply to pump and
thendetachHoseandGunat75367Swivel.
