INSPECTION AND MAINTENANCE
CAUTION
Be sure to disconnect the hose during cleaning jams,
inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) Remove the nail roll from the magazine, open the nail
guide, insert a rod into the outlet and tap the rod with a
hammer (Fig. 18).
(2) Remove the jammed nail with slotted screw driver
(Fig. 19).
(3) In case of frequent jams, consult the Authorized Service
Center from which you bought this machine.
2. Check on mounting screws for each part
At regular intervals check every part for loose mounting
screws and whether or not there are any air leaks.
Retighten any loose screws. Operating the equipment
with loose screws untightened will incur a hazard.
3. Inspecting the push lever
Check if the push lever can slide smoothly (Fig. 20).
Clean up the sliding area of the push lever and use the
provided oil for lubrication from time to time. Lubrication
enables smooth sliding and simultaneously serves to
prevent the formation of rust.
4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then apply
the recommended oil (See Fig. 20).
(2) Open the nail guide and remove dust, etc., as shown
in Fig. 21. Apply lubricant to the sliding groove of the
feeder and shaft. Check the nail stopper slide smoothly
by pushing them with your fi nger.
(3) Also, apply the recommended oil to the feeding sur face
of the nose and nail guide after cleaning. This promotes
smooth operation and retards corrosion.
CAUTION
Check for smooth movement of the feeders and
stoppers before use. If movement is uneven, nails could
be fi red at an irregular angle, presenting a hazard to the
operator and others nearby.
5. Inspect the Trigger
Periodically clean the sliding parts of the trigger, and
make sure that the trigger moves smoothly (Fig. 22).
6. Inspecting the muffl er
This Nailer has a built-in muffl er in the exhaust to reduce
noise and stirred-up dust during exhaust.
When the mesh of the muffl er is fi lled or the muffl er
is damaged, replace the muffl er with a new one. To
replace the muffl er, contact our Authorized Service
Center (Fig. 23).
7. Inspecting the magazine
Clean the magazine. Remove dust of wooden chips
which may have accumulated in the magazine.
8. Storing
○ When not in use for an extended period, apply a thin
coat of the lubricant to the steel parts to avoid rust.
○ Do not store the Nailer in a cold weather environment.
Keep the Nailer in a warm area.
○ When not in use, the Nailer should be stored in a warm
and dry place.
Keep out of reach of children.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
COMPRESSOR
CAUTION
When the maximum, operating pressure of the air
compressor exceeds 23 bar (320 psi), be sure to
provide a reducing valve between the air compressor
and nailer. Then, adjust the air pressure within the
operating range of 12 – 23 bar (170 – 320 psi). If the
air set is installed, lubrication is also possible, thus
providing additional convenience.

Noise Information
Noise characteristic values in accordance with EN ISO
11148-13:2018
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
Uncertainty K: 2.5 dB (A)
These values are tool-related characteristic values and do
not represent the noise development at the point of use.
Noise development at the point of use will for example
depend on the working environment, the workpiece, the
workpiece support and the number of driving operations,
etc.
Depending on the conditions at the workplace and the form
of the workpiece, individual noise attenuation measures
may need to be carried out, such as placing workpieces on
sound-damping supports, preventing workpiece vibration
by means of clamping or covering, adjusting to the minimum
air pressure required for the operaion involved,etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance
with EN ISO 11148-13:2018, 2000: 6.0 m/s
Uncertainty K = 1.5 m/s
2
This values is a tool-related characteristic value and does
not represent the infl uence to the hand-arm-system when
using the tool. An infl uence to the hand-arm-system when
using the tool will for example depend on the gripping
force, the contact pressure force, the working direction, the
adjustment of energy supply, the workpiece, the workpiece
support.
