Electric chain saw is a woodworking electric tool that uses a rotating chain saw blade for cutting. Below, the editor will specifically introduce the safety regulations and general requirements for the use of electric links, tell everyone the preparation work and operation methods during operation, and introduce the maintenance and precautions before operation of electric chain saws. We hope it can be helpful to everyone. Come and take a look!

1. Safety regulations for the use of electric chain saws

1、 Scope: This standard specifies the safety requirements for the use of electric chain saws. This standard is applicable to electric chain saws for timber production in timber yards and other uses of electric chain saws.

2、 Referenced standards? The provisions contained in the following standards, through reference in this standard, constitute the provisions of this standard. At the time of publication of this standard, all versions shown are valid. All standards used will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB 3883.1-1991 Safety of Handheld Electric Power Tools Part 1: General Requirements (for Certification) GB 3883.14-1993 Safety of Handheld Electric Power Tools Part 2: Specific Requirements for Electric Chain Saws

3、 Safety operating procedures?

Warning: Accidental accidents during the use of electric chain saws that cause personal injury and property damage must be borne by the operator and user unit.

General requirements?

The electric chain saw should comply with the provisions of GB 3883.1 and GB 3883.14.

The operator must be familiar with the performance and operating methods of the electric chain saw, and be able to operate and maintain it correctly according to the user manual.

The operator must have received training and hold a work permit, and the following personnel are not allowed to operate the electric chain saw:

a) Minors and elderly people;

b) People who are physically weak or disabled;

c) People who drink or take narcotic drugs.

3.2.4 Do not operate the electric chain saw under the following circumstances:

a) When someone approaches;

b) Before the auxiliary personnel for material production withdraw to a safe area;

c) Unstable stacking of original strips in the work area;

d) Insufficient light;

e) On rainy days, in open spaces with wind speeds greater than level 5 and thunderstorms;

f) When there is no chain breakage protection device or rebound protection device, or when the device is damaged.

prepare

Safety shoes must be worn during homework.

During homework, it is not allowed to wear oversized or open clothes and shorts, as well as accessories such as ties, bracelets, ankles, etc.

3. Carefully check the wear level and tension of components such as the saw chain, guide plate, and sprocket, and make necessary adjustments and replacements.

4. Check whether the electric chain saw switch is intact, whether the power connector is firmly connected, and whether the cable insulation layer is worn.

Thoroughly inspect the work site and remove stones, metal objects, branches, and other discarded materials.

Before starting the operation, it is necessary to select a safe evacuation channel and a safe area.

operation

When the original strip being processed is within 1.5m of the conveyor, operation is not allowed.

Before connecting to the power supply, the electric chain saw switch must be turned off to prevent accidental start-up.

3 Before making materials, start the electric chain saw to idle for 1 min, and check whether it operates normally.

When starting or operating, hands and feet should not be close to rotating parts, especially the upper and lower parts of the chain

When a fuse is blown or a relay trips, immediate inspection should be carried out.

6. Do not overload the circuit and do not connect high-capacity fuses.

The electric chain saw must be operated with both hands.

During homework, it is important to stand firmly and not operate under or on logs that may roll.

When troubleshooting saw clamping faults, special attention should be paid to the safety of auxiliary personnel.

During the operation, the sawing mechanism should be lubricated and cooled at all times.

When the original saw is about to break, pay attention to the movement of the wood and quickly lift the electric chain saw after the cut.

When transferring operations, the electric chain saw switch must be turned off first, and running is not allowed during the transfer.

Immediately cut off the power supply in the following situations:

a) When the saw chain encounters other objects and needs to be checked for damage before restarting;

b) When abnormal sound or vibration occurs during operation and it is necessary to check and troubleshoot;

c) When the operator leaves the electric chain saw;

d) When discovering the movement of nearby logs or logs;

e) When sawing with sawing tools;

f) When leakage is detected;

4、 At the end of the assignment

After daily work, all nuts, bolts, and screws should be tightened, the wear level of the saw chain, guide plate, and sprocket should be checked, and necessary adjustments and replacements should be made.

Check the wear of the power plug and cable insulation layer, and if any damage is found, replace or repair it in a timely manner.

Before long-term storage, residual wood chips and dirt should be cleaned, the saw chain and guide plate should be removed and coated with anti rust oil. The motor should be protected against dust.

It should be stored in a dry environment.

2. Maintenance of electric chain saws

The chain and guide plate should not be too tight. When the electric chain saw is working, lubricating oil should be applied every 10 minutes to not only maintain the guide plate but also the chain. At the same time, the variable box of the electric chain saw also needs to be replaced with yellow glycerin every year, and the motor needs to be replaced with carbon brushes frequently, approximately every six months.

3 Safe operation

Precautions before operation:

1. Safety shoes must be worn during work.

2. During homework, it is not allowed to wear oversized or open clothes and shorts, as well as accessories such as ties, bracelets, ankles, etc.

3. Carefully check the wear level and tension of components such as the saw chain, guide plate, and sprocket, and make necessary adjustments and replacements.

4. Check whether the electric chain saw switch is intact, whether the power connector is firmly connected, and whether the cable insulation layer is worn.

5. Thoroughly inspect the work site and remove stones, metal objects, branches, and other discarded materials.

6. Before starting the operation, it is necessary to select a safe evacuation channel and safety zone.
