Using this SuperLube grease is easy. First, make sure the fuser roller tube or the area you want to lubricate is clean. Remove any dirt or old lubricant. Then, squeeze a small amount of the 85gm (3oz) tube of grease onto the parts. Spread it evenly using a clean tool. When it comes to temperature, remember this grease works well from - 45°F to 450°F, so don't use it in extreme conditions outside this range. Since it's non - toxic, it's generally safe, but still, keep it away from food and drinks. For maintenance, check the lubricated parts regularly. If the grease seems to be drying out or getting dirty, clean the area and re - apply a fresh layer. With over 25 years of experience, we're confident this grease will serve you well.
