Below are some guidelines for solutions to common setting and tooling problems. By following these steps you should
be able to get back into production as quickly as possible if a problem arises:
1) SCREWS BREAK FREQUENTLY –
a) Too much air line pressure. Check the air pressure specs for the thread size you are placing. Adjust downward
accordingly.
b) Make sure operator is holding the tool at a 90 degree angle to the work piece, and not tilting it over to one side.
2) TOOL STALLS BEFORE FULLY PLACING THE INSERT –
a) Be sure there is a bearing assembly in the tool. Check to be sure it is not worn out, and that it is assembled correctly.
Clean in solvent, blow dry and lubricate with recommended grease.
b) Check for quick disconnect fittings with holes of ¼” or 3/16”. These may be too small to allow the necessary volume
into the tool. This is especially critical with the 5/16, 3/8 and ½” thread sizes.
c) Be sure hose I.D. is 5/16”.
d) Not enough air line pressure. Check the air pressure specs for the thread size you are installing. Adjust upward
accordingly. To prevent against unfavorable drops in air pressure, regulated pressure readings should be measured at
or near (within 30 feet) of the tool. This air pressure should be within the recommended range of the tool.
e) Check the condition of the mandrel. Replace, if worn using high quality socket head cap screws.
f) Check to see if other air tools are being used that are starving the insert installation tool.
3) TOOL WILL NOT START/RUN –
a) With air system connected, quickly change from forward to reverse several times.
b) Check your air line and air pressure to assure there is an adequate supply of air to the tool.
c) Remove the complete tool nosepiece. Manually rotate the square drive shaft. Connect air to tool and depress trigger.
d) Evaluate airline set-up portion.
e) If there is an air motor failure, call
Sherex Customer Service.
4) AIR MOTOR RUNS, MANDREL DOESN’T TURN -
a) Make sure hex drive is engaged into the mandrel. Check to see if screw is broken or if the head is rounded out. Check
also, if the hex drive itself has been rounded off. Replace defective parts as may be required to assure proper
installation.
