7. Maintenance
The PowerTrak is designed to operate with a minimum of maintenance. However, the following steps must
be performed on a regular basis to ensure peak performance over the unit's lifetime.
The most crucial maintenance item is lubrication. We recommend using Valvoline Val-Plex EP™ wheel
bearing grease for this purpose. The full length of the screw, and the "V shaped" tracks on the sides of the
cabinet (where the load block runs) should be wiped from top to bottom with grease. There are five grease
fittings provided on the PowerTrak, one on the load nut, and one on the thrust bearing (just above the spider
coupling), and three on the pulleys in the top. Each bearing should receive two pumps with a grease gun (or
until grease appears on both sides of the bearing) at least every 3 months.
To grease the screw, hookup grease gun to the fitting on load nut. Then use the manual setting on the
controller to move load nut from one end of the screw to the other while applying grease. This ensures that
the full range of the load nut is well lubricated.
Important: Do not use WD-40™ or other similar products for lubrication or cleaning of this machine.
Products of this nature will remove grease from the unit, causing excessive wear on load bearing surfaces and
increasing the possibility of binding.
It is also important to keep debris out of the enclosure. The door on the unit should be sufficient, but it is still
recommended that you do a visual inspection and clean out any wasp nests, etc. It is acceptable to blow
debris out of the unit with pressurized air, but never spray the internals with water unless power is completely
disconnected from the unit.
Inspect cables periodically, especially at the onset of cold weather. Damaged cables can break, and the risk
is higher in colder temperature. Replace any badly frayed or excessively worn cables.
