E.T. ET-500-PLUS User Manual - Basic Maintenance
5
The ET-500-PLUS is designed to be maintenance free. However, there are some basic
installation checks that should be carried out regularly (every three months) which
will increase the long term reliability of your equipment and prevent intermittent
operation.
NB: ISOLATE MAINS SUPPLY TO SYSTEM BEFORE CLEANING OR
WORKING ON THE EQUIPMENT
1. GENERAL
1.1 Keep the bottom track clear of stones, dirt and obstructions. Ensure that all rollers
are free, sturdy and no wheel bearing has seized.
1.2 In manual mode, check that the gate runs freely on its track and does not snag
against walls, posts or shrubs.
1.3 Ensure that the gate limits are positioned correctly and the gate does not bang
into either the open or closed end stops during normal operation.
1.4 Keep shrubs and vegetation clear of the motor and upper geared rack.
1.5 Check that the manual override operates freely. Spray with oil if necessary.
1.6 Keep the inside of motor housing clear of insects and dust.
2. THE BATTERY
2.1 The ET -500-PLUS is fi tted with a maintenance-free lead acid battery.
2.2 However, if the motor has been used on battery back-up for extended periods
without charging, the life span of the battery can be shortened. So it is important
that the motor is supplied with its own fi xed household power point and is not
shared where it can be regularly disconnected.
3. PRECAUTIONS
3.1 DO NOT:
a) oil or lubricate the nylon upper geared rack
b) spray insecticides on or near the electric components. Rather
spray insecticides around the base on the outside of the motor.
HOT TIP: Place mothballs in the motor base to minimise infestation of insects and other
creatures.
