5) Service
a. Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure the continued safe operation of the power tool.
2. Diamond Core Drill Safety Warnings
1) Use auxiliary handles supplied with the tool. Auxiliary handles allow for good control and
support safe operation.
2) Consider work area environment: Do not use the diamond core drill in damp or wet
locations. Do not expose diamond core drill to rain. Operate only in a well-lit area. Do not
use in the presence of flammable vapors or liquids. Electrical motors produce sparks during
normal operation.
3) Grounding of Class I tools is necessary while in use to protect the operator from electrical
shock. Class I tools are equipped with an approved three-conductor cord and three-prong
grounding-type plug.
4) Warning! The power outlet must be fitted with proper grounding. Do Not insert Class I
tools into the socket without grounding. Never use a Class I tool with a damaged or missing
ground plug.
5) Use a 12 gauge extension cord when tool is used outdoors or indoors. Use only three-
conductor cord with approved grounding.
6) Be aware of your surroundings when working at elevation. Hard hat and fall protection may
be indicated. Secure the area under and around the work location.
7) Use a garden hose and quick change adapter to supply water to the core bit. The water
valve on the core drill can be used to adjust the water flow.
8) To protect the user and the core drill, ensure that there are no water leaks.
9) Inspect the hoses and other critical parts of the tool for wear. If water leaks from the
testing hole of the gear box, the seal must be repaired immediately to avoid damage to the
machine and possible hazard to the operator.
10) The maximum permitted pressure of water supply is 17 psi.
11) Warning! Never to use the tool without the GFCI provided.
12) Test the correct operation of the GFCI before starting work. The red light will be “ON”
after pressing the “RESET” button. The light will be “OFF” after pressing the “TEST” button.
Only operate the tool when the GFCI works properly.
13) Replacement of the plug or the power cord shall always be carried out by the tool
manufacturer or authorized service center.
14) To ensure the safety of the operator and others, make certain that water is diverted
away from the motor and other electrical equipment. Use a water containment system
where appropriate and when working at elevation.

5. Maintenance
1) Contact an authorized service center for service and repair. Do not use unapproved
replacement parts.
2) Check the electric brushes and commutator periodically. When the brushes are worn to the
about 3/16” they must be changed. Use only original equipment replacement parts to
ensure proper operation and commutator damage. Both brushes must be changed at the
same time. If you find heavy sparking during operation or the commutator is worn or
burned, repair or replace the commutator.
3) The drill should be checked and repaired periodically after use. Check the condition of the
power cord and plug. Verify proper grounding. Replace seals as needed and check
lubricating oil.
4) Replace the rubber seals as required. Stop using the drill immediately if water is flowing
from the top of the drill, please check and replace the sealing washer immediately. The
gears in the gear case use lubricating oil, if you find lubricating oil penetrating the mid-
cover air port, please replace the rubber sealing oil ring on the rotor spindle. The brand of
special lubricating oil is 110# industrial gear oil. Keep the drill clean and dry. When not in
use, store the drill a clean dry place. Remove the core bit when storing the drill. Apply a
small amount of grease to the threads prior to storage.
