Please use the following as a guide to maintaining and running your engine

Before running and during long running sessions

• Oil moving parts using a good quality oil - Brass motor mount bushes, axle boxes, gears and brass bushes on the coupling rods.
  

• Inspect Electrical System
  Inspect wire for damage due to heat and / or abrasions.
  Battery terminals are tight.
  

• If you are carrying large loads please check, motors, control board and wires for signs of excessive heat. If you find any parts are running excessively hot reduce load and allow to cool before using again

Regularly - Before 1st run and at around 5 outings or less i.e. running in dirty conditions

Inspect the gears to check for the following-

• Excessive build up of dirt.

Dirt and grit on the gears will increase wear on both metal and nylon gears. If there is excessive dirt build upclean using a tooth brush, white spirits and a cloth to clean each groove. Once clean take the opportunity to check for damaged teeth or object embedded in the gear.

• Slack

Turn the wheels and check to see if there is any slack between the nylon and metal gears. If there is slacken the motors bolts on the offending motor and move it to reduce the slack. If a motor slips out of alignment or excessive play allowed between the gears the motor may end up stripping the teeth off of the nylon gear.

Regularly -Before 1st run and after around 10 Outings +

• Loose bolts

Check all bolts, nuts (including motors), electrical terminals, crank set grub screws etc for tightness.

• Check wheel sets for excessive wear and flange damage

• Check all bearings/bushes for excessive wear.

STOP and INVESTIGATE

IF -

• You smell electrical burning or see smoke - isolate power before you investigate.

• Change of noise or hear strange noises coming from the engine

• Performance changes dramatically

• See liquid coming from the batteries - see warning notes
