EXPRESS DUAL LIFT TABLE
4. Maintenance and Adjustment
NOTE: Maintenance and adjustment should be carried out by suitably qualified/trained personnel
in accordance with the information in this Manual.
As the conditions and frequency of use will vary greatly the following recommendations
should be modified if required to suit the prevailing circumstances.
The Express Dual Lift Table is designed and constructed to require the minimum of
maintenance. The 3 main requirements are:
1. The correct voltage at the motor terminals when the controls are activated.
2. The correct amount of clean hydraulic fluid of an appropriate grade in the hydraulic system.
3. No build up of dirt or debris around any of the moving parts.
NOTE: When cleaning the Express Dual machine ensure that none of the dust or debris from the
grinding process is allowed to enter the Lift table mechanism.
The following checks should be carried out at approximately the intervals stated:
MONTHLY
Visually check the complete unit, confirm that all fixings are secure, that all electrical
connections are tight, and that the hydraulic fluid is at the correct level with no visible
hydraulic leaks.
3 MONTHLY
In addition to the monthly checks, ensure that the lift platform is level with the Express
Dual table at the top of its travel. Adjust if required using the two adjusters (part#14 on
exploded parts diagram)
12 MONTHLY
In addition to the above checks, ensure that all parts are clean and free from any damage
or obvious wear. Raise the table to the top of its travel and apply a small amount of grease
over the whole length of both chains.
On DC powered units visually check the motor brushes for wear.
NOTE: When any moving parts have been replaced or cleaned with a degreasing agent, ensure
that they are re-assembled with an adequate quantity of medium grease.
