16. Keep all nuts, bolts and screws tight and ensure equipment is in safe working condition.
17. Do not put hands near or under moving parts.
18. Air Hose.
It is not recommended to install a quick coupler between the drill and leader (whip) hose.
Using fittings or air hoses, which are too small can create a pressure drop and reduce the
power of the tool. For 9.525 mm (3/8"), 12.7 mm (1/2") and 8 mm drill, using 9.525 mm (3/8")
I.D. fittings with 6.35 mm (I/4") NPT threads are recommended. Most compressors are
shipped with a short, 6.35 mm (1/4") I.D. hose. For proper performance and more
convenience, use a 9.525 mm (3/8") I.D. hose. Hoses longer than 15.24 m (50 feet) should
have a 12.7 mm (1/2") I.D.
Never carry a tool by the hose or pull the hose to move the tool or a compressor. Keep hoses
away from heat, oil and sharp edges. Replace any hose that is damaged, weak or worn.
19. Storage.
The drill must be lubricated before storing. Follow the air motor lubrication instructions with
an exception to step 4. Only run the drill for 2 to 3 seconds instead of 20 to 30 seconds
because more oil needs to remain in the drill when storing.
2. Particular Safety Instruction
1. Information of Noise Level.
(1) The noise level at the operator's position is about:
Sound Pressure Level : 89.6 ~ 93.2 dB(A).
Sound Power Level : 101.5 ~ 105.7 dB(A).
(2) Reference standard : ISO 3746.
(3) Always wear ear protectors during operation.
2. Information of Vibration Level.
(1)The vibration level at the handle is about : 1.3448~1.588 m/s2.
(2)Reference standard : EN 28662-1.
3. Information of Temperatures.
(1)The temperatures at the handle (8 hours/Operation) is 30º C .
4. Warnings.
(1) The power tools are not generally insulated for coming into contact with electric power sources.
(2) The high reaction torques can be developed in the case of stalling. Stalling can be caused by
excessive loads being applied to the drill bit, the drill bit snags on the material being drilled into or
when the drill bit breaks through the material being drilled.
(3) The unexpected tool movement or breakage of inserted tool may cause injuries to hands or feet.
(4) The unsuitable postures may not allow counteraction of normal or unexpected movement of the
power tool.
