TUNGSTEN CARBIDE BIT, ETC. (Fig. 2, 3, 4, 5, 6)
(Spline shank bit)
1. Position the stopper shaft (2) of tool retainer. (Fig. 2)
2. Insert the bit into the retainer hole (9) and turn it by hand so it can be
correctly aligned. (Fig. 2)
3. Then, push the bit as far as it will go and lock it by pushing the stopper
shaft to the opposite side. (Fig. 3)
4. The bit can be removed by following the above method in reverse.
(Hex. shank bit)
1. Set the hole (10) on the retainer ring (3) at the bottom position by
rotating the retainer ring. (Fig. 4)
2. Insert the bit into the retainer hole (9) as far as it will go. (Fig. 4)
3. Turn the retainer ring counterclockwise until the hole (10) is positioned
at the right side. (Fig. 5)
4. To remove the drill bit, turn the retainer ring clockwise while pushing
the retainer lock button (11) until the small hole (10) is positioned at
the bottom. (Fig. 6)
5. Pull out the bit by a hand.
TAPER SHANK BIT (Fig. 7, 8)
1. Mount the taper shank adapter (6). (Fig. 7)
2. Insert the drill bit into the taper shank adapter and strike the tip of drill
bit with wooden hammer. (Fig. 7)
3. To remove the drill bit, place the drill bit on soft material such as wood

2. Clean up the dust from the drill hole with the blow-out-bulb (13).
3. Set the plug (14) to the tip of anchor and drive it into the hole.
4. Fasten the material to the anchor with a bolt (15).
AUX. HANDLE (Fig. 10)
Aux. handle (4) can be rotated 360 deg.or easy operation.
It is strongly recommended that the aux. handle should be used during all
drilling operations.
DEPTH STOPPER (Fig. 11)
The depth stopper (5) helps to ensure accurate hole depth when drilling
holes.
To drill the desired depth, adjust the depth stopper so that the measure
from the end of it to the tip of bit can be equal to the desired depth.
MAINTENANCE
To ensure safe and proper operation, examine the machine for obvious
damage before and after use. Damaged parts should be repaired or replaced
immediately by an approved RYOBI service organization, using RYOBI
spare parts and materials.
NOTE!
The hammers and rotary hammers require regular servicing.
In regular use, to help know when servicing is required, this machine
is fitted with “automatic cut-off” carbon brushes and these carbon
brushes will automatically stop the machine from running after
approximately 150 operating hours under normal condition of use.
This indicates that the machine requires servicing. The necessary
service and maintenance will include replacing the carbon brushes,
O-rings and grease. This work should be carried out quickly and
expertly by any RYOBI service shops, using genuine RYOBI service
parts.
IMPORTANT
The life time of the carbon brushes depends on the usage and
environmental conditions. Failure to carry out the maintenance work
or failure to use original RYOBI maintenance service parts may cause
malfunction of the machine and this will invalidate your warranty.
SAVE THESE INSTRUCTION FOR FUTURE REFERENCE.
