Maintenance - Makita AN901 Instruction Manual

However when the tool is set to the "Intermittent Nailing"
mode, WITH THE TRIGGER HELD IN A HALF-PULLED
POSITION, an unexpected nailing could occur, if the con-
tact element is allowed to re-contact against the work-
piece or the other surface under the influence of recoil.
In order to avoid this unexpected nailing, perform as fol-
lows;
1. Do not place the contact element against the work-
piece with excessive force.
2. Pull the trigger fully and hold it on for 1 – 2 seconds
after nailing.
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.
For No. 1 method, set the change lever to the "Intermit-
tent Nailing" position. For No. 2 method, set the change
lever to the "Continuous Nailing" position. 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. (Fig. 14)
CAUTION:
• Operating the tool without nails shortens the life of the
tool and should be avoided.
Air exhaust
Air exhaust direction can be changed easily by rotating
the exhaust cover. Change it when necessary.
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. Loose bolt
may cause air leakage from the tool.
• Never hang the tool on a waist belt or like. Dangerous
accidental firing may result. (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 LOCK position. (Fig. 22)
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
lubrication 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 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.

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.
