Drilling metal
There are two rules for drilling hard materials. First, the harder the material, the greater the pressure you
need to apply to the tool. Second, the harder the material, the slower the speed. Here are a couple of tips
for drilling in metal. Lubricate the tip of the bit occasionally with cutting oil except when drilling soft
metals such as aluminum, copper or cast iron. If the hole to be drilled is fairly large, drill a smaller hole
first, then enlarge to the required size, it’s often faster in the long run. Maintain enough pressure to assure
that the bit does not just spin in the hole. This will dull the bit and greatly shorten its life.
RUNNING NUTS AND BOLTS
Variable speed control must be used with caution for driving nuts and bolts with socket set attachments.
The technique is to start slowly, increasing speed as the nut or bolt runs down. Set the nut or bolt snugly
by slowing the drill to a stop. If this procedure is not followed, the tool will have a tendency to torque or
twist in your hands when the nut or bolt seats.
TEMPERATURE CONTROL /OVERLOAD PROTECTION
When the temperature of battery is too high and the machine switches off automatically.
• Switch the power tool off.
• Allow the battery to cool down before continuing to work.
When the power tool is blocked and switches off automatically.
• Remove the power tool from the workpiece.
• As soon as the blockage is corrected, the power tool will continue to work at the set stroke rate.
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.
