Frequently Asked Questions - WFH-1240 Vevor

How to lubricate the Vevor WFH-1240 pneumatic hammer?
Add 2 to 6 drops of pneumatic tool oil into the air inlet before each workday or after 2 hours of continuous use. Use the provided oil injector if necessary.
What air pressure is recommended for the WFH-1240?
The maximum allowable pressure is 90 PSI (6.3 bar). Start at the lower end of the recommended range.
What accessories are included with the drill?
The kit includes: 4 x 7 mm scrapers (round heads), 3 air connectors (Europe, USA, Australia), 1 round spring scraper seat and 1 oil injector.
How to install the air connector on the hammer?
Choose the connector suitable for your country (EU/US/AU). Screw it onto the tool's air inlet. If using an oil injector, install it between the connector and the tool in the order shown in the diagram.
What to do if the tool does not work properly?
First check the air pressure and that the compressor is on. Inspect the air inlet for obstructions. If the problem persists, disassemble and clean the internal parts (valve, piston) or replace worn O-rings.
What safety precautions should I take?
Always wear safety glasses and hearing protection. Never point the chisel at a person. Disconnect the tool from the compressor before any adjustment or maintenance. Use only dry, clean compressed air.
How to change the chisel on the WFH-1240?
Disconnect the tool from the compressor. Remove the spring scraper seat (if present). Insert the suitable chisel (0.401 inch round shank) into the front part and lock it by turning the damping spring.
Can the hammer be used without an oil injector?
Yes, but manual lubrication is necessary: add 2-6 drops of oil into the air inlet before each use. The oil injector automates this process.
Where can I find spare parts for this model?
Spare parts are listed in the diagram in the manual (ref. WFH-1240-01 to WFR-1060-02). Contact the manufacturer or an authorized Vevor dealer to order O-rings, pistons, etc.
What is the chisel blow rate per minute?
The hammer delivers 2700 blows per minute (BPM) at the recommended air pressure of 90 PSI.

Should the oil injector remain permanently attached to the WFH-1240 chisel?
Frequently Asked Questions - 23/05/2026
Response Notice-Facile

No, the oil injector is not mandatory at all times. According to the Vevor WFH-1240 manual, the oil injector is optional and its necessity depends on your actual use of the tool.

Two options for lubricating your chisel:

  • With the oil injector: The injector provided with the tool can be installed by unscrewing its screws and connecting it to the 1/4 inch air inlet. It offers continuous automatic lubrication.
  • Without injector (manual lubrication): You can remove the injector and manually add 2 to 6 drops of pneumatic oil into the air inlet before each workday or after 8 hours of continuous use.

Practical tip: If you use the chisel intensely and regularly, the built-in injector simplifies maintenance. For occasional use, a few manual drops are more than sufficient. Pneumatic tool lubrication oil must be purchased separately.

What air pressure is required on the compressor to use the Vevor WFH-1240 chisel?
Frequently Asked Questions - 21/05/2026
Response Notice-Facile

Required pressure: 6.3 bars (90 PSI)

The Vevor WFH-1240 pneumatic chisel requires a minimum pressure of 6.3 bars on your compressor to operate correctly. This is equivalent to 90 PSI in imperial units.

Technical details:

  • Operating pressure: 6.3 bars
  • Air connection: 1/4 inch
  • Blow rate: 2,700 blows per minute

Important advice: Ensure that your compressor provides at least 6.3 bars continuously during use. A compressor that is too weak will reduce the impact power and efficiency of the chisel. Also, make sure to use the 1/4 inch connector provided with the tool.

Maintenance: Remember to lubricate the tool regularly by adding 2 to 6 drops of pneumatic tool oil into the air inlet before each workday.

What are the 7 mm scrapers provided with the Vevor WFH-1240 drill used for?
Frequently Asked Questions - 21/05/2026
Response Notice-Facile

The Vevor WFH-1240 pneumatic hammer (not a drill) comes with 4 round-headed scrapers, specially designed for scraping, shearing, and finishing on various surfaces.

The main uses of the scrapers are:

  • Scraping and cleaning - Removing rust, paint layers, adhesive residues, mortar, or ingrained deposits from surfaces
  • Precise shearing - Cutting or removing rivets, joints, burrs, and other elements attached to wood, metal, and plastic
  • Finishing and refining - Cleaning and smoothing surfaces after machining, demolition, or material removal
  • Light demolition - Removing tiles, mortar, or other adhesive materials in construction

These scrapers operate at a striking speed of 2700 blows per minute and require an air pressure of 90 PSI (6.3 bars). They can be easily mounted in the tool's nose via the provided round spring scraper seat and can be quickly changed to adapt the work to your needs.

For optimal operation, regularly check that the scrapers are not worn, and lubricate the tool by adding 2 to 6 drops of pneumatic oil before each workday or after 2 hours of continuous use. Wear protective gloves and safety glasses when using.
