Frequently Asked Questions - HB920D Cocraft

How do I change the blade on the Cocraft HB920D saw?

First, unplug the saw. Press the spindle lock to prevent the blade from rotating. Use the provided wrench to loosen the arbor nut (turn clockwise as viewed from the blade side). Remove the outer flange and old blade. Install the new blade with teeth facing the rotation direction (indicated on the guard). Reassemble and tighten the nut securely while holding the spindle lock.

How do I adjust the depth of cut?

Loosen the depth adjustment lever located near the base plate. Slide the base plate up or down to set the desired depth. The scale shows the cutting depth. Retighten the lever. For most materials, set the blade to extend about 5 mm below the workpiece thickness.

Can I use the HB920D to cut metal?

Yes, but you must use a ferrous metal cutting blade (e.g., diamond or carbide-tipped). Reduce the sawing speed and apply light pressure. Always wear appropriate PPE, including safety glasses and gloves. Ensure the material is securely clamped.

How should I clean and maintain the saw?

After each use, unplug and wipe the saw with a dry cloth. Use compressed air to blow dust from the motor vents and blade guard. Periodically check the carbon brushes: if they are worn down to less than 6 mm, replace both brushes. Lubricate the bevel mechanism with light oil if needed.

What should I do if the saw doesn't start?

Check the power cord and plug for damage. Ensure the outlet is live. Verify that the safety lock-off button is disengaged. If the saw still won't start, the brushes may be worn or the switch faulty. Contact Cocraft service for repair.

How do I use the laser guide?

The laser guide projects a red line indicating the cut path. Slide the laser switch to the ON position. The laser is factory-set; if it needs adjustment, use the screws near the laser housing to align the line with the blade's cut. The laser requires two AAA batteries (not included).

When should I replace the carbon brushes?

Replace the carbon brushes when they are worn to less than 6 mm in length, or if the saw sparks excessively. Always replace both brushes at the same time. Use genuine Cocraft brushes (part number available in the manual). Insert the new brushes with the curved side against the commutator.

What is the warranty period for the Cocraft HB920D?

The standard warranty is 2 years from the date of purchase, covering manufacturing defects. It does not cover normal wear and tear, misuse, or damage from unauthorized repairs. Keep your receipt as proof of purchase.

Can I use an extension cord with this saw?

Yes, but use a heavy-duty cord rated for at least 15 amps and suitable for outdoor use if necessary. Keep the extension cord as short as possible to avoid voltage drop. Do not use cords longer than 30 meters (100 feet). Ensure the cord is fully unwound to prevent overheating.

What is the maximum cutting capacity of the saw?

At 90° (perpendicular to the base), the saw can cut up to 65 mm depth. At a 45° bevel, the maximum cut depth is 45 mm. For panel sawing, the width is limited only by the workpiece size; use a guide rail for long cuts.

Safety

General Power Tool Safety Warnings

WARNING Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application.
The correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Repairs and service should only be performed by qualified persons, and only with original spare parts. This guarantees the safety of the electrical hand tool.

Specific Safety Regulations for Belt Sanders

• Hold power tool by insulated gripping surfaces, because the belt may contact its own cord. Cutting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
• Wear safety goggles and a dust mask whenever sanding. Prolonged exposure to the dust caused by sanding is detrimental to your health; certain types of wood dust are toxic and hazardous even after minimal exposure.
  • Make sure that the sanding belt is intact and well centred.
• Make sure that the sanding belt is not touching anything when switching the machine on. Switch it on and let it come up to speed before starting to sand.
• Hold the machine firmly in both hands.
  • Make sure that there are no nails or foreign bodies in the workpiece before starting to sand.
• Keep the air vents of the motor clean and free of obstructions to prevent the motor from overheating.
• Wear a dust mask whenever sanding and a dust extractor connected to the machine should also be used wherever possible.
• Extra care should be taken when sanding paint containing lead or when sanding wood, metal, or other material which could produce toxic dust. Make sure that anyone in the vicinity of the work area is also protected from dust and toxins.
• Wood dust can be very flammable when mixed with air.

Warning: Never use the extractor when sanding metal, sparks could ignite the hose or dust bag.

Vibration

• The measurement of the vibration emission level declared in this instruction manual has been carried out in accordance with a standardised test method described in EN 60745 and can be used for comparing one power tool with another.
• The measurement method may also be used for a preliminary assessment of vibration exposure.
• The declared vibration emission level applies when the power tool is used in accordance with this instruction manual. If however, the power tool is used for other purposes and with other accessories or has not been properly maintained, the vibration emission level could increase significantly over the total working period.
• For an exact assessment of the vibration exposure, the times when the tool is switched off or running idle should also be taken into account. This significantly reduces the vibration exposure over the total working period. Decide upon safety measures to protect the operator from the effects of vibration during all types of use.

Guide to Safety Symbols

Read the entire instruction manual.

Always use ear protection, safety glasses or a visor and wear a dust mask.
