PM Inspections are extremely important to the lifetime of your fleet and equipment. A good Preventative maintenance program includes 4 inspections a year, chassis greasing, on time oil changes and DOT Inspections. A well trained technician will be able to inspect all components of your equipment for wear and damages. It’s a lot cheaper to replace a worn out set of tires during one of these inspections than it is to replace it on the roadside. To determine which component should be replaced and what is functioning properly takes years of experience. Here at The Block Mechanics Inc. we have over 10 years of experience.
