DAILY CHECKLIST
1. Check engine oil level in tow vehicle. Add as needed. DO NOT OVERFILL.

3. Check hardware for loose or missing nuts, bolts, screws, etc., and tighten or replace as needed.
4. Inspect hydraulic lines for damage or leaks. Never use hands to inspect leaks.
5. Check hydraulic fluid level in tank. Look at the sight gauge on the front left side of the tank. The oil level
should be at 90°C (194°F). If level is low, add SAE 10W-40 API Service SJ or higher motor oil.
6. Check controls for smooth, proper working operation. Lubricate as needed.
7. Check and clean all debris from blower housing.
ADJUSTMENT OF BELT TENSIONER
There are four maximum belt tensioners on the Big Vac. Two control the ten-
sion on the belts on the blower housing, one each on the finger reel and the
thatcher reel. The proper tension of the idler should be 12 to 15 as per the
gauge (A) on the side of the tightener. Over tightening the belt will shorten the
life of the belt and the machine may not perform to the best of its ability. To ad-
just belt tensioner, loosen bolt holding tensioner. Bring idler pulley tight to belts
and turn tensioner into belts to 15°. Tighten holder bolt.
CONTROL PANEL ADJUSTMENT ARM
On the right hand side of machine is the
adjustment lock arm, by lifting up you
can adjust the control panel by moving
it forward or rearward. Make certain that
the lock arm is locked back in place after
adjustment. For up and down adjustment
loosen the four adjustment bolts place the
control panel to where you want it and
tighten the four bolts.
