Maintenance - Ryobi P250 Manuel D'utilisation

 If the bit jams in the workpiece or if the drill stalls, stop
the tool immediately. Remove the bit from the workpiece
and determine the reason for jamming.
NOTE: This drill has an electric brake. When the switch trig-
ger is released, the chuck stops turning. When the brake is
functioning properly, sparks will be visible through the vent
slots on the housing. This is normal and is the action of the
brake.
WOOD DRILLING
For maximum performance, use high speed steel bits for
wood drilling.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. Increase the speed as the
drill bit bites into the material.
 When drilling through holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power product operation or when blowing
dust. If operation is dusty, also wear a dust mask.
WARNING:
To avoid serious personal injury, always remove the
battery pack from the product when cleaning or
performing any maintenance.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.

OPERATION
METAL DRILLING
For maximum performance, use high speed steel bits for
metal or steel drilling.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit. Also, lubricate the bit with oil
to improve drilling action and increase bit life.

MAINTENANCE

Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc., come in contact
with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal
injury.
Only the parts shown on the parts list are intended to be
repaired or replaced by the customer. All other parts should
be replaced at an Authorized Service Center.
BATTERy PACk REMOVAL AND PREPARATION
FOR RECyCLING
Upon removal, cover the battery pack's terminals with
heavy-duty adhesive tape. Do not attempt to destroy or
disassemble battery pack or remove any of its compo-
nents. Lithium-ion and nickel-cadmium batteries must
be recycled or disposed of properly. Also, never touch
both terminals with metal objects and/or body parts as
short circuit may result. Keep away from children. Failure
to comply with these warnings could result in fire and/
or serious injury.
