Reminders for Utilizing the hydraulic breaker/hydraulic hammer in Winter

Dec 22 , 2023

Firstly, when operating the hydraulic breaker/hydraulic hammer in low-temperature seasons:

1. Prior to operating the hydraulic breaker/hydraulic hammer, warm up the machine for 5-10 minutes on a low setting, and select relatively soft stones for impact. Once the hydraulic oil temperature rises to an appropriate level (the optimal working oil temperature for the hydraulic breaker/hydraulic hammer is 50-70°), switch to the normal working gear.

2. Prior to the demolition operation, stand the hammer upright, press the chisel tip down to the ground, then lift it, repeating this action no less than 5 times. The purpose is to ensure that the cylinder, piston, oil seal, and other components are fully lubricated.

3. After each work stoppage, store the hydraulic breaker/hydraulic hammer vertically with the chisel bracing the ground, pressing the piston into the interior of the cylinder. This prevents the formation of water vapor in the striking chamber of the front cylinder due to large temperature differences, which could cause the exposed part of the piston to rust and lead to oil leakage and other malfunctions.


Secondly, when the hydraulic breaker/hydraulic hammer is temporarily or briefly out of operation:

1. Never lay the hydraulic breaker/hydraulic hammer flat, as the weight of the piston falling on the oil seal can cause the oil seal to deform or get damaged. In such cases, when you want to operate the hydraulic breaker/hydraulic hammer, it could lead to oil leakage or the piston of the oil cylinder being pulled up.

2. The hydraulic breaker/hydraulic hammer should be kept vertical, with the chisel bracing the ground, keeping the piston inside the cylinder. This prevents contamination or high humidity in the air from causing the exposed part of the piston to rust and corrode, and the cylinder piston to get damaged.


Thirdly, when hydraulic breaker/hydraulic hammer is out of operation for a long period of time:

1. Plug the oil inlet and outlet to prevent the entry of dirt.

2. Remove the chisel.

3. Lay the hydraulic breaker/hydraulic hammer flat on a dry and flat ground, with the rear part of the hammer body placed on a wooden pillow higher than the front part to maintain ventilation.

4. Completely release the nitrogen in the rear cylinder.

5. Push the piston into the interior of the middle cylinder.

6. Apply lubricating grease or anti-rust oil to the front end of the piston, the chisel, and the inner and outer sleeves.

7. Cover the entire hammer body with a tarpaulin or store it indoors

For hydraulic breaker/hydraulic hammer that have been stored for a long time or during the rainy season, they must be disassembled, maintained, and inspected by professionals before being used again. Seals must be replaced before they can be installed and used.
