4.3   PHYSICAL INSPECTION

Once the machine is located, check it for any possible damage incurred in shipment. Remove the lifting 

eyelet and install the draw handle. 

⌦

CAUTION: DO NOT USE THE LIFTING EYELET FOR ANY MACHINES OTHER THAN 

THIS SAW. MAKE SURE THAT THE DRAW HANDLE HAS A JAM NUT ON THE 

THREADS BEFORE INSTALLING IT ON THE SAW. IF THE HANDLE IS INSTALLED 

WITHOUT THE JAM NUT, IT MAY CONTACT THE GEARS INSIDE THE HEAD.

After the draw handle has been installed on manual and power vise machines, remove the cover from the 

electrical control box and connect the trigger switch wires. Remove any other packing material and 

draw the saw head to its DOWN position to make sure that the guard opens properly. The guard should 

close completely when the head is up and open freely as the head travels down. If the guard is not 

functioning properly, REFER TO SECTION 4.6 for the manual machines or SECTION 7.2C for 

machines equipped with the power down feed option. With the head in the DOWN position, check the oil 

level in the gear box through the sight glass in the casting just below the draw handle. If your saw is 

equipped with either the power vise or the power down feed option, REFER TO SECTIONS 7.1 THRU 

7.2, for additional information.
