Operating

1. Adjusting Flow Rate

The DGP180Z features a two-speed flow rate selector dial:

• Setting 1 (Low Speed): Provides a slower, more controlled grease output, ideal for precise applications or when less grease is required.
• Setting 2 (High Speed): Delivers a faster grease output for quick lubrication of larger components or when speed is a priority.

Rotate the dial to select the desired flow rate before operating the tool.

2. Lubrication Procedure

1. Ensure the grease gun is primed and ready for use.
2. Firmly attach the coupler at the end of the flexible hose to the grease fitting on the component to be lubricated. Ensure a tight seal to prevent leakage.
3. Press the trigger switch to begin dispensing grease.
4. For continuous operation, press the lock-on button while the trigger is depressed. Press the trigger again to release the lock-on.
5. Observe the component being lubricated. Stop dispensing grease when resistance is felt or when the desired amount of grease has been applied.
6. To detach the coupler, twist it slightly while pulling it straight off the fitting.
