Operation guide
Maintain good balance on both feet. Keep proper distance from the chisel of the Rock Drill.
Never put your hand near the rod when using the Rock Drill horizontally.
Push the Rock Drill against the object firmly using the handle before turning the throttle valve level.
Obey the law and safety regulations.
CAUTION：Pressing the Rock Drill with proper force
Pressing the Rock Drill on the object too strong, much load is applied to
rotation parts and these parts wear out quickly.
It depends on the rock quality but basically the maximum pressing force at
vertical drilling is 50kgf.
If the Rock Drill is used for a long time with higher pressing force than
maximum value, it might lead to the quick wear or premature failure for internal
parts.
Conversely, if pressing force is too weak, the Rock Drill works intensely and
cause high vibration.
Then it might lead to high burden and early fatigue for workers, and lead to
quick wear for the consumable parts.
Inspection and maintenance
WARNING
Turn valve cock of the compressor to the stop position first, turn the throttle valve level of the Rock Drill and
release the excess pressure in the air hose completely, then disconnect the Rock Drill from the air hose and
finally inspect the Rock Drill.
Inspection and storage for a Rock Drill
Clean the exterior surface using a cloth.
Regularly inspect the tightening torque on the bolts.
Inspect whether there are any cracks or damage in the Rock Drill.
Storage of the Rock Drill
Apply 3 cc of oil from the air inlet. operate the Rock Drill for about 5 seconds after completing work.
Repeat above operation 2-3 times before storing the Rock Drill.
Put a cap on the air inlet of the Rock Drill to prevent any dust or foreign material from entering the
Rock Drill. Keep the Rock Drill in a dry place.
Loss of power/erratic action (possible causes)
1. Reduced compressor output.
2. Excessive drain on air line.
3. Moisture or restricted pipe, hose or fittings.
4. Improper size or poor condition of pipe, hose or fittings.
5. Incorrect shank size of chisel, or excessively worn shank.
6. Free running (or blank blow) can cause damage to the tool. Always hold the tool down to the work.
7. Loosening of side bolts or back head bolts will cause loss of power and can cause damage to the tool.
Periodic inspection of bolt torque at regular intervals (at least once a week if tool is being used regularly)
is recommended.
If everything else appears to be in order, then disassemble tool, replace worn or damaged parts, clean,
reassemble and lubricate.
Replacement parts
Always use GENUINE TOKU TOOL Replacement Parts.
When replacement parts are required, order by Part Number and Description from the Parts List.
