3. Setup and Assembly
The GRYVOZE Pneumatic Oil Gun Dispenser is designed for straightforward setup. Follow these steps for initial assembly and connection:
- Unpack Components: Carefully remove all items from the packaging. Verify that all included components are present: 1 x Oil Control Valve, 1 x PTFE Tape, 1 x Oil-absorbing Cloth.
- Connect Air Supply Hose: Attach your air supply hose to the 1/2-inch NPT inlet connection at the base of the dispenser handle. Use the provided PTFE tape on the threads to ensure a secure, leak-free seal. The 360-degree rotating inlet allows for flexible hose positioning.

4. Operating Instructions
Operating the GRYVOZE Pneumatic Oil Gun Dispenser is designed for convenience and precision.
- Prepare for Dispensing: Ensure the dispenser is securely connected to both the air and fluid supply. Position the 90-degree oil nozzle over the target receptacle. The flexible hose can be bent to fit tight spaces.
- Initiate Flow: Squeeze the ergonomic handle to begin dispensing fluid. The anti-drip design helps prevent spills.
- Hands-Free Operation (Optional): For extended dispensing, engage the manual locking switch on the handle. This will maintain a steady oil flow without continuous pressure on the trigger.
- Stop Flow: Release the handle to stop the fluid flow. If the locking switch was engaged, disengage it first.
- Post-Operation: After use, ensure the fluid supply is closed and disconnect the air supply.

- Verify that the trigger is fully depressed or the locking switch is engaged.
- Leaking from Connections:
- Tighten all connections.
- Ensure PTFE tape was properly applied to threaded connections.
- Inspect O-rings and seals for damage and replace if needed.
- Reduced Flow Rate:
- Check the air pressure; it should be within the recommended operating range.
- Clean the inlet filter.
- Ensure the fluid being dispensed is within the applicable viscosity range.
If problems persist after attempting these steps, please contact GRYVOZE customer support.
