OPERATING TIPS
Hold the tool firmly and place the point of the driver bit in the screw head. Apply forward pressure to the
tool to the extent that the bit will not slip off the screw and turn the tool on to start operation.
CAUTION:
• Use the proper bit for the head of the screw/bolt that you wish to use.
• Hold the tool pointed straight at the screw.
• If the impact force is too strong or you tighten the screw for too long time, the screw or
the point of the driver bit may be over stressed, stripped, damaged, etc. Before starting your job, always
perform a test operation to determine the proper fastening time for your screw.
Apply the power tool to the screw/nut only when it is switched off. Rotating tool inserts can slip off.
The torque depends on the impact duration. The maximum achieved torque results from the sum of all
individual torques achieved through impact. The maximum torque is achieved after an impact duration of
3-5 seconds. After this duration, the tightening torque is increased only minimally.
The fastening torque is affected by a wide variety of factors including the following. After fastening,
always check the torque with a torque wrench.
•
Strength properties of the screws/nuts.
• Type of backing (washer, disc spring, seal).
• Strength properties of the material being screwed/bolted together.
• Lubrication conditions at the screw/bolt connection.
IMPORTANT CHARGING NOTES
WARNING:
Battery packs are shipped in a low charge condition to prevent possible
problems. Therefore, you should charge them before first use.
• Use only POWERSMART battery charger (Model#PS76018C)
• Charge time is approximately 1hour, and is dependent upon the type of battery pack.
• Make sure the power supply is normal household voltage, 120V, AC only, 60Hz.
• Attach the battery pack to the charger by aligning the raised ribs on the battery pack with the grooves
in the charger, then slide the battery pack onto the charger.
• Press down on the battery pack to be sure contacts on the battery pack engage properly with contacts
in the charger. Latches should snap into ensure charger is correctly connected.
• Do not place the charger in an area of extreme heat or cold. It will work best at normal room
temperature.
• The battery pack may become slightly warm to the touch while charging. This is normal and does not
indicate a problem.
• The red LEDs will remain on while charging.
• When the green LEDs is light, this indicates the battery is fully charged.
• To remove the battery pack from the charger, depress latches and pull up on the battery pack.
• When the battery pack is fully charged, remove it from the charger.
