• After every use, check the blades for damage, and if necessary, grind off / file away any burrs that
are visible on the cutting edge.

• Check the couplers for damage. Have a Holmatro Certified Technician replace damaged couplers.
• Clean the coupler with luke warm water and a mild soap solution.

• Lubricate the end of the coupler with hydraulic oil or inject WD-40.
