Jammed nailer (Fig. 15)
CAUTION:
• Always lock the trigger, disconnect the hose and
remove the nails from the magazine before cleaning a
jam.
When the nailer becomes jammed, do as follows:
Open the door and magazine cap and remove the nail
coil. Insert a small rod or the like into the ejection port
and tap it with a hammer to drive out the nail jamming
from the ejection port. Reset the nail coil and close the
magazine cap and door.
Hook (Fig. 16)
The hook is convenient for hanging the tool temporarily.
This hook can be installed on either side of the tool.
CAUTION:
• Always lock the trigger and disconnect the hose when
hanging the tool using the hook.
• Always tighten the hook securing bolt firmly.
• Never hang the tool on a waist belt or like. Dangerous
accidental firing may result. (Fig. 17)
Nails
Handle nail strips 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 air hose from the tool before
attempting to perform inspection or maintenance.
Maintenance of nailer
Always check the tool for its overall condition and loose
screws before operation. Tighten as required. (Fig. 20)
Make sure all safety systems are in working order before
operation. The tool must not operate if only the trigger is
pulled or if only the contact element is pressed against
the wood. It must work only when both actions are per-
formed. Test for possible faulty operation with nails
unloaded.
Entering dirt or foreign matter into the tool may cause
damage to the tool. (Fig. 21 & 22)
Make sure that the trigger is locked when the change
lever is set to the LOCK position. (Fig. 23)
When not in use, lock the trigger and disconnect the
hose. Then cap the air fitting with the cap. (Fig. 24)
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. 25 & 26)
Iron dust that adhere to the magnet can be blown off by
using an air duster. (Fig. 27)

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. 28 & 29)
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. 30)
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. 31)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be per-
formed by Makita Authorized Service Centers, always
using Makita replacement parts.
