Even if you take good care of your unit and perform proper maintenance routinely, you eventually will need to replace equipment. But how do you know when it is time to replace? "I would say the most obvious sign, and it's kind of like with a car or anything else, is once it starts giving you a lot of trouble," Loutzenhiser says.
Rayner agrees. "Machines, unlike humans, cannot regenerate or repair their internal workings. Eventually they just wear out." If you fix one problem and just move onto another, replacement may be the best course of action.
To keep sealcoating equipment running at peak efficiency, follow this to-do-list suggested by Seal-Rite, Neal Manufacturing, and RaynGuard.
- Check and clean filter pot
- Check all lubricants every morning
- Check engine for oil level, cleanliness, secure mounts, and leaks
- Check cooling system for clean, unobstructed coolant level at proper height
- Check hydraulic system for leaks
- Check hydraulic hoses for creases, bends or chaffed areas as well as seeping or leaking spots
- If you use a trailer: check the lug nuts on the wheels, the tire pressure, and also the lights
- Check the hose next to the spray wand- if it is soft, cut it off and reattach the spray wand
- Change battery as needed
- Monitor the piston pump for dried sealer on the top - this indicates the pump leathers are wearing and need replacing
