OPERATION

CAUTION:
• Be sure to set the change lever to the LOCK position to
avoid unexpected misfiring when the tool is not in use.
• Make sure all safety systems are in working order
before operation. (Fig. 14)
Only pulling trigger without contact element contacting
workpiece must not bring about the tool firing. (Fig. 15)
Only contact element contacting workpiece without pulling
trigger must not bring about the tool firing. (Fig. 16)
This nailer is only for intermittent pin-driving. Intermittent
pin-driving is a method of pinning piece by piece with the
following step.
1. Set the change lever to the FREE position.
2. Place the contact element against the workpiece
3. And then pull the trigger.
Pin-driving of concrete
WARNING:
• Use hardened pins only for concrete.
Using other purposed pins may cause serious injuries.
Do not pin directly on the concrete. Failure to do so
may cause concrete fragments to fly off or pins to strike
back, causing serious injuries.
• When driving pins, hold the tool so that it stands upright
to the driving surface.
Slanted pin-driving may cause concrete fragments to
fly off or pins to strike back, causing serious injuries.
• Do not use on the surface that objects hang from, such
as area where hangers for sewer pipe, dust pipe etc.
are set up.
Choose and use pins so that the penetration amount
into concrete ranges 15 mm - 20 mm. (Fig. 17)
CAUTION:
• Use this tool only for soft concrete built up not so long
before. Using on the hard concrete may cause pin
bending or pin-driving to insufficient depth.
• When the penetration amount into concrete is required
more than 20 mm, driving pins to the sufficient length
may not be obtained. Pins may be driven too shallow
causing unstable workpiece, resulting in personal injury
and damage to property.
Cutting off the sheet
CAUTION:
• Always disconnect the hose before cutting off the
sheet. (Fig. 18)
Tear off the output sheet in the direction of the arrow when
using the sheet collated pins.

MAINTENANCE

CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
Jammed nailer
CAUTION:
• Always disconnect the air hose and remove the pins
from the magazine before cleaning a jam. (Fig. 19 &
20)
When the nailer becomes jammed, do as follows:
Open the magazine cap and remove the pin coil. Insert a
small rod or the like into the ejection port and tap it with a
hammer to drive out the pin jamming from the ejection
port. Reset the pin coil and close the magazine cap.
Drain tool (Fig. 21)
Remove the hose from the tool. Place the tool so that the
air fitting faces down to the floor. Drain as much as
possible.
Cleaning of tool
Blow off dust adherent to the tool by using an air duster.
Cap (Fig. 22)
When not in use, disconnect the hose. Then cap the air
fitting with the cap.
Storage
When not in use, the nailer should be stored in a warm
and dry place.
Maintenance of compressor, air set and air hose.
(Fig. 23 & 24)
After operation, always drain the compressor tank and the
air filter. If moisture is allowed to enter the tool, It may
result in poor performance and possible tool failure.
Check regularly to see if there is sufficient pneumatic oil in
the oiler of the air set. Failure to maintain sufficient
lubrication will cause O-rings to wear quickly. (Fig. 25)
Keep the air hose away from heat (over 60°C, over
140°F), away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacles which it
may become dangerously caught on during operation.
Hoses must also be directed away from sharp edges and
areas which may lead to damage or abrasion to the hose.
(Fig. 26)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
