How often should I grease the front end of the GR29 Grinder?Stanley recommends removing the front end of the tool after every 10 hours of operation to ensure the grease has not hardened. If you suspect the grease to not be working, you will need to remove the old grease from the front end of the tool and repack it with 7 pumps of new grease.
Will my tool operate if I use a lower flow rate than what would be considered optimum for the tool to operate?Yes, most tools have an optimal flow range, as long as the gallons per minute delivered to the tool is within this range the tool will work. However, please be award that the tool will run at a slower speed based on the flow rated delivered to the tool. Basically, the lower the gallons per minute the slower the tool will run.
