ALWAYS check equipment for proper operation before each use,
making sure safety devices are in place and operating properly. DO
NOT alter or modify any part of the equipment as this may cause a
malfunction and result in serious bodily injury.
BEFORE CONNECTING AIR MOTOR TO AIR
LINE
LINCOLN SERIES Ill AIRMOTORS are fully pneumatic and require a
minimum specied size of air supply hose for proper operation. Check
specication for minimum ID. of the air supply hose and select cor-
responding sizes of air controls and accessories for non-restrictive air
ow. Lincoln lter, regulator with gauge and lubricators are available
as combination units (FRL).
For 3/8” air line - Model 85387-6
For 1/2” air line - Model 85387-8
For 3/4” air line - Model 85387-12
If quick disconnect coupling should be used, install supplied coupler to
insure proper airmotor operation.
NOTE: Whenever ammable materials are pumped, ground Airmotor
according to Local Codes.
OPERATING PRECAUTIONS
Use Lincoln replacement parts to assure compatible pressure rating.
Heed ALL warnings.
DO NOT OPERATE Airmotor in excess of recommended pressure
ALWAYS read and follow the uid and solvent manufacturer’s rec-
ommendations regarding the use of protective clothing and equip-
ment.
To reduce the risk of serious bodily injury or property damage.
NEVER exceed the maximum air or uid working pressure of the
lowest rated system component.
ATTACHING AIRMOTOR TO PUMPTUBE
1 Tightly attach the tie rods (ltem 41) to the Airmotor lower casting.
Use short threaded end of tie rods.
2. Mount Airmotor on top of pump tube outlet and tightly connect
pump tube coupling nut to Airmotor Piston Rod (Item 5).
3. Hand tighten tie rods to the pump tube with four nuts (Item 42)
supplied with Airmotor.
4. Connect air supply and slowly cycle pump several times using only
enough air pressure to operate pump without stalling.
5. STOP pump on “UP” stroke and tighten four nuts to securely fas-
ten Airmotor to pump tube.
range.
Disconnect air line and relieve (vent) pressure when Airmotor sits idle
for long periods of time and before servicing.
