The MotoMaster Suction Grease Gun is a great addition to the handyman, mechanic, or service technician’s toolbox. Anytime you need to remove or add fluid to a reservoir, this simple device is ready to go to work for you. It saves you time by quickly providing access to service fluids and not having to take the extra time to disassemble and drain. Simply insert the included hose into the reservoir and pull out on the follower handle. Each pull will remove up to 510 g / 533 cc of fluid. Similarly, refilling difficult to reach reservoirs, the user pulls up to 510 g / 30 cc of fluid into the Suction Gun and then after inserting the hose, pushes the follower handle to dispense the fluid. This simple and dependable design is intended to provide years of trouble-free use.
