OPERATION

SWITCH LOCK

See Figure 5.
The trigger switch can be locked in the OFF position.
This feature can be used to prevent the possibility of
accidental starting when not in use. To lock the trigger
switch, place the rotation selector (Forward / Reverse
Selector) in the center position.

Note: When the selector is in center position, trigger
switch is locked.

REVERSE

See Figure 5.

This tool has the feature of reversible rotation, that is
controlled by a selector located above the trigger switch
(6).

■

Clockwise rotation: set the selector lever to the left

position (16).

■

Anti-clockwise rotation: set the selector lever to the

right position (15).

MODE SELECTOR

■

For drilling, place the selector in the position.

■

For hammer drilling, set to

The switch-over can best be performed at a standstill.
Only after the switch is actuated and the machine starts
does the gear box shift to the selected mode.

Note: Hammer drilling mode will damage the tool’s
mechanism when used for fastening or drilling by a
non-SDS plus bit. Select the drill mode only for such
purposes.

When hammer drilling, use exclusively bits with hard
metal and SDS-Plus shaft only. The use of commercially
available masonry bits with cylindrical by means of the
drill adapter is impossible.

HAMMER DRILLING

When hammer drilling, you do not need to apply

too much pressure. The performance is not
increased in this manner. Too much pressure will
place unnecessary load on the motor.

Check the drill bits regularly. Re-sharpen or

replace blunt drill bits.

For hammer drilling, work only with protective glasses,
hearing protection and the auxiliary handle.

FITTING AND CHANGING SDS BITS

See Figure 6.

This tool is equipped with an SDS-plus connection
system.

■

Clean the bit and grease it with machine grease

before inserting it into the chuck (2).

■

Pull back the clamp collar (3) and hold it.

■

Push and rotate the bit into the bit holder as far as it

will go.

■

Release the clamp collar to lock the bit.

■

Check that bit has locked by pulling on it.

REMOVING THE BIT FROM THE SDS-PLUS

SYSTEM

Pull back the clamp collar and remove the bit.

35mm CHUCK ADAPTOR (NOT INCLUDED)

See Figure 6.

For drilling work in metal , wood and plastic with drill
bits that have a Non SDS Plus shaft, the drill adaptor is
available.

PRACTICAL TIPS

Check the area of work before drilling in case of hidden
electrical lines or gas and water pipes.

SLIP CLUTCH

If the tool becomes jammed or gets caught, the slip clutch
releases.

Remove the load from the machine immediately by
pulling back the drilling tool.

Always hold the machine tightly with both hands

and assume a secure stance.

MAINTENANCE

WARNING:

When servicing, use only identical Ryobi
replacement parts. Use of any other parts may
create a hazard or cause product damage.

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.
