ASSEMBLY & 

BREAK-IN PROCEDURES

ASSEMBLY AND LOCATION OF THE AIR COMPRESSOR 

 
Your compressor requires some minor assembly. Install both 10” wheels (A) 
Fig.3 using axle bolts, spring washers, washers and hex. nuts supplied. 
Then install the rubber foot (B) using a large hex. bolt and hex. nut. Install 
handle (C) to the tank and secure handle using 2 set screws (D). 
 
Operate the air compressor in a dry, clean, cool, well ventilated area. The air 
compressor pump and case are designed to allow for proper cooling.  Clean 
or blow off dust or dirt that collects on the air compressor. A clean air          
compressor runs cooler and provides longer service. The ventilation        
openings on your air compressor are necessary to maintain proper           
operating temperature. Do not place rags or other containers on or near 
these openings. 
 

 

 

 

*IMPORTANT BREAK-IN PROCEDURES* 

 

NOTE: SERIOUS DAMAGE MAY RESULT IF THE FOLLOWING      
BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED. THESE 
PROCEDURES ARE REQUIRED BEFORE THE AIR COMPRESSOR CAN 
BE PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE, AND 
WHEN A PISTON OR A CYLINDER SLEEVE ARE REPLACED. 

 
1) Make sure the pressure switch On/Off lever (A) Fig.4 is in the “OFF”    

position as shown. 

 
2) Plug the power cord into a grounded 120V branch circuit receptacle. 
 
3) Make sure the oil level in the crankcase reaches the centre dot of the oil 

sight glass (A) Fig.5, refer to maintenance section for instructions on       
filling the crankcase with oil.  

 
4) Open the drain valve lever (A) Fig.6, turn it counterclockwise, this will        

prevent air pressure build-up in the tank.  

 
5) Move the pressure switch On/Off lever (A) Fig.4 down to “ON/AUTO” 

position. The compressor will start.  

 
6) Run the compressor for 15 minutes. Make sure the drain valve is open 

and there is no tank pressure build-up (tank pressure gauge at zero). 

 
7) After 15 minutes, close the drain valve by turning it clockwise. The air 

receiver will fill tank to cut-out pressure and the motor then will stop. The 
air compressor is now ready for use.
