Depress the nail stopper and remove the strip of nails
from the magazine. (Fig. 11)
Connecting air hose (Fig. 12)
Lock the trigger. Slip the air socket of the air hose onto the
air fitting on the nailer. Be sure that the air socket locks
firmly into position when installed onto the air fitting. A
hose coupling must be installed on or near the tool in such
a way that the pressure reservoir will discharge at the time
the air supply coupling is disconnected.
OPERATION (Fig. 13 - 15)
CAUTION:
• Make sure all safety systems are in working order
before operation.
1. To drive a nail, you may place the contact element
against the workpiece and pull the trigger, or
2. Pull the trigger first and then place the contact element
against the workpiece.
• No. 1 method is for intermittent nailing, when you wish
to drive a nail carefully and very accurately.
No. 2 method is for continuous nailing.
CAUTION:
• However when the tool is set to the "Intermittent Nail-
ing" mode, WITH THE TRIGGER HELD IN A HALF-
PULLED POSITION, an unexpected nailing could
occur, if contact element is allowed to re-contact
against the workpiece or the other surface under the
influence of recoil.
In order to avoid this unexpected nailing, perform as
follows;
A. Do not place the contact element against the workpiece
with excessive force.
B. Pull the trigger fully and hold it on for 1-2 seconds after
nailing.
• For No. 1 method, set the change lever to the
tion.
For No. 2 method, set the change lever to the
tion. After using the change lever to change the nailing
method, always make sure that the change lever is
properly set to the position for the desired nailing
method.
Anti dry fire mechanism
This tool is equipped with an anti dry fire mechanism.
When there are a few nails remaining in the magazine,
the contact arm will be locked in the undepressed position
to prevent the tool from being activated. Load more nails
to resume operation.
Jammed nailer
When the nailer becomes jammed, do as follows:
Insert a small rod or the like into the ejection port and tap
it with a hammer to retract the driver. (Fig. 16)
Use pliers to bend the jammed nail so that the nail head
comes out of the slot in the driver guide. Then remove the
jammed nail. (Fig. 17)
Nails
Handle nail coils and their box carefully. If the nail coils
have been handled roughly, they may be out of shape or
their connector breaks, causing poor nail feed. (Fig. 18)
Avoid storing nails in a very humid or hot place or place
exposed to direct sunlight. (Fig. 19)

MAINTENANCE

CAUTION:
• Always disconnect the hose before attempting to per-
form inspection or maintenance.
Maintenance of nailer
Always check the tool for its overall condition and loose
screws before operation. Tighten as required. (Fig. 20)
With tool disconnected, make daily inspection to assure
free movement of the contact element and trigger. Do not
use tool if the contact element or trigger sticks or binds.
(Fig. 21)
Make sure that the trigger is locked when the change
lever is set to the
When the tool is not to be used for an extended period of
time, lubricate the tool using pneumatic tool oil and store
the tool in a safe place. Avoid exposure to direct sunlight
and/or humid or hot environment. (Fig. 23 & 24)
Maintenance of compressor, air set and
air hose
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.
(Fig. 25 & 26)
Check regularly to see if there is sufficient pneumatic oil in
the oiler of the air set. Failure to maintain sufficient lubri-
cation will cause O-rings to wear quickly. (Fig. 27)
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
posi-
may become dangerously caught on during operation.
Hoses must also be directed away from sharp edges and
posi-
areas which may lead to damage or abrasion to the hose.
(Fig. 28)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance and adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
