2. Setup
Initial Charging
Before using the clipper for the first time, it must be fully charged. Plug the power cord directly into the unit and then into an appropriate power outlet. Ensure the clipper is switched OFF during charging. The charge indicator light will illuminate during charging and begin to blink when almost fully charged. A full charge from a discharged battery takes approximately 3-3.5 hours.

Attaching Guide Combs
To attach the guide combs, hold the comb with its teeth facing upwards and snap it firmly onto the bottom of the clipper blade. Ensure it is securely in place before use.
Blade Adjustment (Taper Lever)
Some clippers are equipped with an adjustable taper lever that changes the closeness of your cut. When the lever is in the uppermost position, the blades will give the closest cut (approximately 0.5mm). Pushing the lever downward gradually increases the cutting length up to 1.0mm.

3. Operating Instructions
Powering On/Off
To switch on the clipper, locate the ON/OFF switch (refer to Product Components diagram) and slide it to the 'ON' position. To turn off, slide the switch to the 'OFF' position.
Corded/Cordless Operation
- Cordless Use: The unit can be used without a cord when fully charged. A full charge provides up to 85-90 minutes of operating time.
- Corded Use: If the battery power is low, or for continuous use, attach the power cord directly to the unit and plug it into an outlet. Ensure the clipper is switched OFF when connecting the cord. If the battery is completely drained, allow the unit to charge for 1 minute (while switched OFF) before using it as a corded unit.
- Automatic Charging: If the cord is left attached to the unit when not in use, and the clipper is in the OFF position, the unit will automatically charge.
Hair Cutting
For uniform cutting, allow the clipper to cut its way through the hair. Do not force it through at a faster rate. Use the appropriate guide comb for your desired hair length.
4. Maintenance
Cleaning the Blades
Regular cleaning ensures optimal performance and hygiene. After each use, switch off the clipper and disconnect it from the power supply. Use the provided cleaning brush to remove any hair clippings from the blades. The blades can be washed under water.
Lubrication
Although an oil bottle is included in the packing list, lubricants are not provided by the seller due to aviation logistics restrictions. It is recommended to periodically lubricate the blades with clipper oil to maintain their sharpness and smooth operation. Apply a small drop of oil to the blades and run the clipper for a few seconds to distribute the oil.
Changing the Blade Set
Warning! Injuries and material damage due to incorrect handling.
- Switch the appliance off using the on/off switch and disconnect from the power supply.
- Undo the screws on the blade set. A Torx T20 screwdriver may be required. Remove the bottom blade and the top blade.
- The blade can now be removed for cleaning or replacement.
- To re-assemble, place the top blade on the plastic cam.
- Position the bottom blade and reinsert the two screws.
- Before tightening the screws, align the bottom blade so that there is a gap of 0.5mm to 1.0mm between the front edge of the bottom blade and the front edge of the top blade.
- Tighten the screws. No blade alignment is required once the Torx screws are tightened, as the blade will automatically align in the correct position.
Do not use the appliance if the teeth are damaged or missing from the blade or if the blades are misaligned, as injury may occur.
5. Troubleshooting
If your cordless clipper does not seem to be operating or charging properly, check the following:
- Power Outlet: Check the outlet's current by plugging in another appliance that you know is in proper working condition.
- Power Source: Ensure the unit is not connected to a power source that turns itself off (e.g., a switched outlet controlled by a light switch).
- Contacts: Make sure the clipper and charging transformer contacts are clean and free of hair or other contaminants.
- Blade Assembly: Verify that the blade assembly moves freely and is mounted properly.
