CDM1H HAND-HELD CORE DRILL — SHUTDOWN/MAINTENANCE
Shutdown
1. Remove the power cord from the wall receptacle or power
source.
2. Allow a sufficient amount of time for the core drill bit to cool
before attempting to remove it from the core drill.
3. Using the wrenches as illustrated in Figure 4, remove the
core drill bit from the drill.
4. Clean the drill bit with a mild cleaning solution, removing
dirt and foreign matter.
5. Once the core drill has been cleaned, place the core drill
into its carrying case along with all associated hardware. Be
sure to wrap the power cord neatly into the carrying case.
This will extend the life of the cord.
6. Store the carrying case out of the reach of children, in a
location that is moisture free.
Maintenance
1. The CDM1H basically is maintenance-free. The only
maintenance requirement is to periodically check the main
gear grease level.
2. Using the supplied 5 mm allen wrench, remove the grease
plug as shown in Figure11.

3. Visually inspect to see if grease is present. It may be
necessary to insert a small blade screw driver or similar
device into the filler hole to determine if the grease level is
low.
4. If the grease level is low, apply 1 shot of
lithium base grease,
grade N0.1. DO NOT over fill.
5. Reinstall grease plug and tighten securely.
