EXCESSIVE VIBRATION

WILL OCCUR IF THE COMPRESSOR IS
NOT PROPERLY MOUNTED

 OR IF THE

ENGINE OPERATES ABOVE RECOM-
MENDED RPM.

ATTACHMENTS  & ACCESSORIES

EXCEEDING THE PRESSURE RATING OF AIR
TOOLS,

 SPRAY GUNS, AIR OPERATED

ACCESSORIES, TIRES AND OTHER
INFLATABLES 

CAN CAUSE THEM TO EX-

PLODE

 OR FLY APART, AND COULD RESULT

IN SERIOUS INJURY.

TURN ENGINE OFF AND ALLOW IT TO
COOL BEFORE ADDING FUEL TO THE
TANK.

  EQUIP AREA OF OPERATION WITH A

FIRE EXTINGUISHER CERTIFIED TO HANDLE
GASOLINE OR FUEL FIRES.

ADD FUEL OUTDOORS

 OR IN A WELL

VENTILATED AREA.  MAKE SURE THERE ARE
NO SOURCES OF IGNITION, SUCH AS
CIGARETTES NEAR REFUELING LOCATION.

OPERATE COMPRESSOR

DO NOT REMOVE THE STIFFENER BAR

CONNECTING THE COMPRESSOR PUMP TO
THE ENGINE, EXCEPT TO ADJUST BELT
TENSION, THEN SECURELY TIGHTEN THE
STIFFNER BAR NUTS.  

THIS BAR CON-

TROLS OUTFIT VIBRATION.

FOR ESSENTIAL CONTROL OF AIR PRES-
SURE, YOU MUST 

INSTALL A PRESSURE

REGULATOR AND PRESSURE GAUGE TO
THE AIR OUTLET

 OF YOUR

COMPRESSOR.FOLLOW THE EQUIPMENT
MANUFACTURERS RECOMMENDATION AND
NEVER EXCEED THE MAXIMUM ALLOWABLE
PRESSURE RATING OF ATTACHMENTS.
