Drive Chain Adjustment
(Figure 13)
1. Premature wear of the drive chain can be
caused by too much tension. It is therefore
important that the chain not be tightened to
the maximum.
2. To adjust the chain tension, unscrew the
3/8"NC nylon insert locknut (item 1) and
move the chain idler up with enough
pressure to sufficiently tense the chain and
tighten the nut (item 1). Make a mark with a
pencil then unscrew the nut and lower the
idler between 3/32" and 1/8" and retighten
the nut (item 1).
Gearbox Oil Level and Oil Change
(Figures 14-14a-14b)
1. Check the oil level before the first use and
after every 40 hours of use. The oil level
must be checked by the breather located
on the top of the gearbox (item 2). Place
the broom on a flat and level surface and
turn it off a few minutes before checking.
2. Remove the breather (item 1), wipe the
stick and reinstall the breather and remove
it once more. The oil level should be
between the 2 lower lines on the breather
stick as shown on figure 14a
3. The oil must be changed every 100 hours
of operation using SAE 80W90, AGMA
5EP oil or the equivalent.
4. To change the oil, place a container under
the gearbox and remove the plug (item 3)
located under the gearbox and let the oil
drain completely.
5. Reinstall the plug (item 3), remove the
breather (item 1) and add the new oil
(approximately 425 ml)
