Keeping the Bite in Trenchers

Trenchers must perform in conditions ranging from loose sand to hard rock. Without proper upkeep, however, the machines might as well be working in quicksand.

Vermeer utility trenchers, such as the V5750 ride-on and V1150 walk-behind, are no exceptions. Regular maintenance and service checks ensure the machines stand up to the rigors of the rental and construction industries, Vermeer says. The company offers basic maintenance advice to ensure a long, productive working life for trenchers:

  • Greasing is one of the most important procedures an owner or renter can do for the machine. Rental center customers should be well-versed in what, where and when to grease.

  • Similarly, changing air filters is crucial, and in many cases, replacing the used filters instead of cleaning them is more effective. Contractors who work in adverse conditions should check the filters every few hours.

  • Finally, changing oil regularly is the best deterrent against contamination regardless of the ground conditions.



Avoid the Shock When Charging Batteries

Each battery cell has a mixture of hydrogen and oxygen, gases that can explode when exposed to a torch, match flame, lighted cigarette or sparks. To lessen the risk of injury, the Rental Industry Association offers the following safety tips:

Work in a safe environment

  • Charge batteries in a cool, dry, well-ventilated room.

  • Do not smoke around the charging battery.

  • Wear protective clothing and use protective equipment, including a face shield, an apron and gloves.

  • Remove rings, watches and bracelets when handling batteries.



The right tools for the job

  • Use insulated tools when working with batteries to help prevent a short or sparks that can cause an explosion or shock.

  • Use an explosion-proof flashlight when inspecting battery chambers. Even a three-cell flashlight can spark an explosion.



In case of accidents

  • If battery acid gets on your face or in your eyes, immediately flush with cool, clean water for at least five minutes and seek medical attention. Do not use eye drops or other medication unless advised by a doctor.

  • If battery acid is spilled on the equipment surface, neutralize with a solution of baking soda and water, and then rinse with clean water.
