① between Grinder and three-point air filtration devices must be installed.
② before each use and prolonged use process， please go into trickle a few drops of lubricating oil in the high-speed gas nozzle.
③ clamping wheel to firmly and carefully inspect the wheel for cracks and defects.
The maximum allowable outer diameter 10MM ④ wheel.
Rotate the switch from OFF to ON ⑤ use direction， trim wheel beating at medium speed of rotation， rotation to the ON position after another， after starting work at full speed.
⑥ If the long-term need this tool please Pour oil to prevent corrosion from the gas nozzle and the front slot.
If you go to find fault ⑦ manufacturer designated repair station maintenance， do not disassemble， so as not to affect the mechanical precision.
⑧ tool clamping can cause improper shock， when this happens， repeat the setup once.
Pneumatic tools Care and Maintenance:
Pneumatic tool maintenance than maintenance， operations and maintenance personnel to develop the habit if the tool life will be greatly improved， most no tools for maintenance or lack of maintenance knowledge， tools do not work or even cause damage.
Maintenance projects are:
① from the tool air inlet filling pneumatic tools before and after each use 3-4 drops of pneumatic tools for oil to reduce wear and extend tool life.;
. ② to seep through the installation of the gas supply source， a guaranteed supply of tools， air dry， and free of impurities;
. ③ regular cleaning， refueling and maintenance， and adjust the appropriate operating pressure， the timely replacement of worn parts;
④. Should not apply anti-rust oil tools， and clogging intake and other exposed holes to prevent dirt from entering the internal tools.
Pneumatic tool should conduct regular safety inspections of the projects are:
. ⑤ air supply hose and fittings should be connected tightly， not loose leak: the inlet valve should be sealed good， flexible switch， the entire gas path seal without leakage.
⑥. Air supply line should be intact， if worn aging， corrosion and other defects and local leak， bulge phenomenon should be replaced immediately.
⑦. Check the guards， if worn， cracks or bending should be replaced.
⑧. Check the working parts are in good condition， if any cracks， defects should be replaced immediately.
⑨. Check tool operating speed and is in good condition. Rotary tools should ensure that the tool is rotated in a good balance， impact tools should ensure that their anti-loose fastening means always intact.
Pneumatic Tools Troubleshooting:
Pneumatic tool during use， due to normal wear and tear， improper workers to operate， or man other factors that may cause the tool to malfunction.
★ fault the general performance of reciprocating pneumatic instruments are as follows: Fixed， reciprocating distance of less or weakness. Wearing parts as: O-ring， piston， cylinder， intake switch， spring.
★ rotary tools malfunction general performance of the tool stuck， do not rotate or turn weakness， failure-prone components as: blades， bearings， housings， cylinder block， the switch assembly， impact block， impact bars， etc.
