Care, Maintenance And Storage - Cocraft LXC series Original Bedienungsanleitung

Variable speed power trigger
1. Slide the battery into the battery connector (1) and make sure that it clicks securely
into place.
2. The rotary hammer drill is started and stopped by holding or releasing the power trigger (10).
3. The rotary hammer drill is equipped with a variable speed control, which makes
it extremely practical for screw driving. The more the power trigger is pressed,
the greater the speed of the tool.
Drilling tips and advice
• When using the hammer only mode, you should only apply light pressure to
the drill. The application of too much pressure can reduce the hammer effect.
Try applying different amounts of pressure until you find the most effective one.
• Check the condition of the drill bit regularly. Replace any worn drill bits/tools.
• Hold the rotary hammer drill perpendicular to the workpiece before starting to drill
(look from several angles). Make sure that you keep the drill straight, do not force
the drill out of line when drilling.
• If you are drilling into thin materials it is important that you place a small piece of
waste material behind the hole to be drilled, otherwise there is a risk of burring
on the back.
• When drilling into metal you should first use a centre punch to make a small
indentation at the spot where you wish to drill. The indentation will prevent
the point of the drill bit from wandering.
• Let the drill bit spin whilst lifting it out after drilling through, it allows the motor
to cool down and the drill bit is freed of dust and debris.
Overload protection and other safety features
The battery has a number of safety features to prevent damage to the rotary hammer
drill and battery during use.
• During short high-load situations the overload protection may turn the rotary
hammer drill off. This protection resets automatically. Release the trigger, wait
a few seconds, ensure that there is no load and then restart the rotary hammer
drill. The rotary hammer drill should now function normally again.
• If subjected to a high-load for an extended period the overheating protection may
turn the rotary hammer drill off. This feature is self-resetting but the rotary hammer
drill cannot be restarted until it has returned to normal operating temperature.
Let the rotary hammer drill/battery cool properly before trying to start working again.
Adverse temperatures can occur in direct sunlight and should therefore be avoided.
• The battery has a deep discharge undervoltage protection device which operates
when the battery becomes discharged. The undervoltage protection device turns
the rotary hammer drill off automatically and the battery then needs to be recharged.

Care, maintenance and storage

Always remove the battery from the rotary hammer drill before performing
any adjustment, service or maintenance.
