5. Precautions on use
The following precautions must be observed to ensure that the performance and
service life of this tool are maintained.
(1) Use the correct compressed air pressure
Use compressed air at a pressure in the range 0.5~0.6 MPa .
WARNING!
If the compressed air pressure used exceeds the range above, this tool will break
down and accident or injury could result.
If the pressure is below the range, the tool may be unable to fasten Pop Nuts fully.
Use a regulator to ensure compressed air supply in the correct pressure range. (See
p.7)
(2) Use an air filter
If the compressed air supplied contains dirt or moisture, it will have an adverse
effect on the tool, so use an air filter in the air supply. (See p.7)
(3) Use a lubricator
This tool needs periodical lubrication. If the tool goes without an adequate supply of
lubricant, its service life will be shortened. (Refer to the following examples of
trouble.)
Install a lubricator within 3m of the tool and adjust its drip rate.
(Recommended drip volume = 1~2 drops for 10
〜
20 nuts fastening). (See p.7)
【
Note
】
Use lubricate oil endorsed by its manufacturer.
（
e.g.
：
for SMC AL series, turbin oil ISO VG32
）
【
Note
】
When the hose length is over 3m of tool or its connection is improper,
lubricant may be unable to be supplied fully.
【
Note
】
When a lubricator is not able to install within 3m of tool, supply lubricate
oil to coupler plug after every 500 nuts fastening.
* Refer to p.21 for detail of lubrication to coupler.
【
Examples of trouble
】
An insufficient supply of lubricant or a mixing of moisture and dust
to compressed air may cause following trouble.
●
Malfunction of valves inside nut tool
e.g.
：
mandrel rotation (normal/reverse) not stop,
not rotate (normal/reverse),
damage of control nut or T-valve push rod, etc.
●
Malfunction of air motor
（
e.g.
：
decrease of air motor revolutions, burned and stucked
）
●
Early degradation of seals (e.g.
：
leakage of compressed air)
