Loosen the axis of the track tensioning roller (Fig. 12.3, 1) Allen
key 8 mm and 17 mm wrench.
2.
Using a 13 mm key, loosen the locknuts (Fig. 12.3, 2) and make a
few turns.
3.
Using a 4 mm Allen key, screw in the tensioner screws (Fig. 12.3,
3) by the same number of turns (for left and right tracks).

Chain lubrication
The lubrication on the drive chains loses its properties when mixed with
road dust. Additional lubrication is required with use.
Clean the chain with paper towels before renewing the lubricant. Then
the wheelchair is transferred to the "On tracks" mode and lubrication is
applied in any way to the inner surface of the chain. Clean the chain with
paper towels before renewing the lubricant. Then the wheelchair is
switched to the "On tracks" mode and the inner surface of the chain is
coated with grease in any way. To distribute the lubricant to all the links
of the chain, drive a short distance on the wheelchair and lubricate
again. To obtain the greatest effect, the operation of lubricating and
moving (in any mode) the wheelchair should be carried out several
times.
