Maintenance
Trailer
Inspect the trailer before every use.
Check all electrical connections to ensure that they are in good working order and replace
where necessary.
Check the trailer lighting board for correct operation. The trailer must not be used until the
lighting board is functioning correctly.
Check the tire pressure and tire tread of each tire on the trailer.
Mast
Weekly place a few drops of oil at the top of each mast section using the oilier on each
collar to ensure smooth operation.
Like any mechanical device, the mast should be used regularly to keep everything in good
working order. Long periods of inactivity can have an adverse effect on the working parts.
Rainwater can enter the mast by running down the sections but will not affect the mast in
any way. However, keep the drain holes clear.
After some years the PTFE bearing material and Nylon keys may require replacement.
NOTE: Please refer to the Mast Manual supplied with the Mast for detailed maintenance
instructions.
