CHARGING

Before using the power tool, charge the battery as follows.

1. Insert the battery into the charger

Insert the battery firmly while observing its direction, until it contacts the bottom of the charger (See Fig. 2).

CAUTION

The UC7SD model is the exclusively designed charger. These cannot charge batteries except the specified batteries. It is possible to insert the batteries other than the specified into the charger and some of them may light up the pilot lamps. However, you are requested to exercise utmost caution not to charge batteries other than specified ones because these can not only be charged but also such actions can result in the malfunction of chargers.

2. Connect the charger power cord to the receptacle

Connecting the power cord will turn on the charger (the pilot lamp lights up).

CAUTION

If the pilot lamp does not light up, pull out the power cord from the receptacle and check the battery mounting condition.

About 60 minutes is required to fully charge the battery at a temperature of about 20^ C. The pilot lamp goes off to indicate that the battery is fully charged. The battery charging time becomes longer when a temperature is low or the voltage of the power source is too low. When the pilot lamp does not go off even if more than 120 minutes have elapsed after starting of the charging, stop the charging and contact your HiKOKI AUTHORIZED SERVICE CENTER.

CAUTION

If the battery is heated due to direct sunlight, etc., just after operation, the charger pilot lamp may not light up. At that time, cool the battery first, then start charging.

3. Disconnect the charger power cord from the receptacle

4. Hold the charger firmly and pull out the battery NOTE

After charging, pull out batteries from the charger first, and then keep the batteries properly.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

(1) Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
(2) Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

When depressing the nail outlet, be sure to fully lift the push lever (See Fig. 15) to release the safety lock. Thus, nails cannot be driven without releasing the safety lock even though the trigger is pulled.

The machine employs a preventive mechanism for unloaded operation.

The machine enters a state where the push lever cannot be pushed up. This takes place when the magazine is not loaded with nails or when the remaining number of nails becomes less than 3.

CAUTION

○Do not drive a nail on another nail.

○Use caution not to throw the push lever tip onto workpiece when the push lever cannot be pushed up.

NOTE

○Under low temperature conditions, the tool sometimes does not operate correctly. Always operate the tool at the appropriate ambient temperature.

2. Clearing a jam

WARNING

○Handle with care to avoid burning yourself, since the nails and nose may become very hot.

If nails are jammed in firing head, remove it, and adjust the nailing in the following order.

①Remove the fuel cell and the battery from the Nailer. (See Fig. 16)

②Lock follower back in magazine and remove fasteners.
③Loosen the knob and lower toward the handle. (See Fig. 17)
④Pull magazine away from the firing head, and clear jam. (See Fig. 18)
⑤Connect the fuel cell and the battery to the Nailer. ALWAYS WEAR SAFETY GLASSES.

HOW TO USE THE NOSE CAP

WARNING

Before attaching or removing the nose cap, be sure to take your finger off the trigger and remove the fuel cell and battery.

NOTE

Keep the nose cap on when driving nails into slippery materials such as thin steel sheets.

○Remove the nose cap when driving nails into wood.

(1) Removing/Attaching the nose cap

The nose cap is attached simply by pressing it onto the push lever. (See Fig. 19)

To remove, insert a screwdriver or similar into the gap between the nose cap and the push lever and lever off. (See Fig. 20)

INSPECTION AND MAINTENANCE

CAUTION

Be sure to remove the battery and fuel cell during clearing jams, inspection, maintenance and cleaning.

1. Inspecting the magazine

①DISCONNECT BATTERY and FUEL CELL.
②Clean the magazine. Remove any plastic chips and concrete dust which may have accumulated in the magazine. Lubricate it with HiKOKI gas strip nailer lubricant.
2. Check on mounting screws for each part

At regular intervals check every part for loose mounting screws. Retighten any loose screws. Operating the equipment with loose screws untightened will incur a hazard.

1. Inspecting the push lever

Check if the push lever can slide smoothly. 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.

1. Storing (See page 8)

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 tool in a warm area.
○When not in use, the tool should be stored in a warm and dry place.

Keep out of reach of children.

This Parts List will be helpful if presented with the tool to the HiKOKI Authorized Service Center when requesting repair or other maintenance.

In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country must be observed.

MODIFICATIONS

HiKOKI Power Tools are constantly being improved and modified to incorporate the latest technological advancements.

Accordingly, some parts may be changed without prior notice.

APPLICABLE LUBRICANTS

Use HiKOKI Gas Nailer lubricant.

Do not use detergent oil or additives.

These lubricants will harm the O-rings and other rubber parts. This will cause the tool malfunction.

Noise Information

Noise characteristic values in accordance with EN 792-13, JUNE, 2000:

The typical A-weighted single-event sound power level

$$ L _ {W A}, 1 \mathrm{s}, \mathrm{d} = 1 0 8 \mathrm{dB} $$

The typical A-weighted single-event emission sound pressure level at work station L_pA1s,d = 99 dB

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, etc.

In special cases it is necessary to wear hearing protection equipment.

Vibration Information

The typical vibration characteristic value in accordance with EN 792-13, JUNE, 2000: 3.5 m/s ^4

This values is a tool-related characteristic value and does not represent the influence to the hand-arm-system when using the tool. An influence 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 wrokpiece support.
