POWERGUN® 18V Li Ion 3.0 Ah battery powered grease gun built with Australian conditions in mind. This heavy duty grease gun combines the power and portability of high spec 18V Li Ion battery technology with the robust durability of cast alloy and steel pressure components to produce a product capable of serving in the most demanding conditions. Fitted with an illumination LED, a 1m long flexible grease hose and Macnaught’s legendary KY High Pressure Grease Coupler even the most difficult to locate and access grease points are within reach. Free standing or slung from the included shoulder strap the gun is easier to handle and generated less fatigue for the operator and the high/low volume valve lets the operator move grease quickly or at high pressure depending on the demand. Incorporating Macnaught’s heavy gauge steel 450gram stepped barrel, this grease gun is capable of dispensing from standard 450 gram grease cartridges or via bulk fill and bleeding is made easy by the spring loaded bleed valve. Included in the smart carry case is a spare 18V Li Ion battery for added longevity and portability and a 90 minute fast charger to keep the tool working.
