Working hints for your tool
Reduce the pressure on the drill bit when it is about to break through.
This will prevent the drill from jamming.
When drilling a large hole, first drill a pilot hole using a smaller drill bit.
Always apply pressure to your drill bit in a straight line, and if possible
at right angles to the workpiece.
Never change the operating mode whilst the drill is running.
Do not apply excessive pressure to the tool when chiseling. Expressive
force does not speed up the work.
Maintenance
Remove the plug from the socket before carrying out any
adjustment, servicing or maintenance.
There are no user serviceable parts in your power tool. Never use
water or chemical cleaners to clean your power tool. Wipe clean with
a dry cloth. Always store your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working controls free of dust.
Occasionally you may see sparks through the ventilation slots. This is
normal and will not damage your power tool.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons in order to
avoid a hazard.
Trouble shooting
The following table gives checks and actions that you can perform if
your machine does not operate correctly.
If these do not identify/solve the problem, contact WORX Customer
Service.
I would add a comment here to again recommend that you apply
grease to the shank of every drill bit used. 1
