PTOSAFETYWARNINGS
1. Alwaysdisengage the PTO, shut off engine and removethekeys before leaving the tractor seat.
2. Keep the tractor's master shield in place at all times.
3. Missing or damaged shieldingis the main reasonfor driveline entanglement. Keep All Guards onandin
goodcondition. Check guardsfrequently.
4. Never stepacross a rotatingpowershaft.Alwayswalk around the revolving shafteven if guards arein
place.
5. Dress for safety. Do not wear loose fitting clothes or jewelry and keep long hair covered or pulled back.
6. Thetractor drawbar should be adjusted to thelengthspecified in the driven machine's manual. This will
helpprevent driveline stressandseparation on uneventerrainand in tight turns.
7. APTO shaft may break or separate during operation if improperlyinstalledoradjusted. Be sure PTO shaft
is installed properly.
8. Neverperform maintenance oradjustments until boththe driveline andthemachinery have stopped
moving.
9. Warnanyone who might come nearan operating PTO about the entanglementhazard.
10. Regularly test driveline guards by spinning or rotating them to ensure the have not become stuck to the
shaft.
11. Always usethe driveline recommendedfor your machine.Neverswitch drivelinesamongdifferent ma-
chines.

Introduction
SETUP
The Big Vac arrives from with some setup required.
1. The PTO shaft and the rubber boot that goes around the blower and the reel need to be installed.
2. You will need a 40 HP (minimum) tow vehicle to remove the Big Vac from the trailer.
a. Clevis Hitch - You will need a 3/4diameter by 4" pin with some type of lock.
b. Ball Hitch (optional) - You will need a 25/16" ball and a locking pin for the coupler.
3. Crank the jack on the Big Vac up so you can hook to tow vehicle.
4. Check the tire pressure. Big Vac: 18 psi (1.3 bar) Castor Wheels: 20 psi (1.4 bar).
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-40API Service SJ or
higher motor oil.
6. Machine should be greased before starting. See Maintenance part of manual.
7. Lower reel all the way down. Place rubber boot onto the bottom of the blower housing.
Raise the reel up 3/4 of the way. Stretch rubber boot around lip on reel. Lift and lower
several times to ensure boot is on properly.
8. When installing PTO shaft be sure the end with the tractor decal (72-087) goes to the tow
vehicle. If PTO Shaft is put on wrong it will bust when engaged.
9. Read operating instructions before starting.
OVERLOADINGDEBRISHOPPERANDWEARONVACUUMHOUSING
OVERLOAINGDEBRIS HOPPER
Smithco Sweeper-Vacs are designed to carry the following maximum loads:
Model 72-000 Big Vac 1500 lbs. (608 kg)
PLEASENOTETHEFOLLOWING:
1. Loads heavier than that will damage the unit.
2. Such damage is not covered by warranty.
3. Overloading is particularly easy when collecting aerifier cores.
4. The hoppers on the Big Vac and V62 are large in order to hold 7 and 4 cubic yards respectively, of thatch, grass
clippings, leaves and trash.
5. They will not hold 7 or 4 cubic yards of aerifier cores.
6. The maximum depth (in the debris hopper) of aerifier cores is:
Model 72-000 Big Vac 12 in. (30 cm)
VACUUM HOUSING WEAR
The Big Vac & V62 are fitted with a wear resistant liner in the vacuum housing. This will provide additional husing life.
Be sure the following points are explained to the user:
1. The vacuum housing and impeller must be cleaned each time the unit is used so the housing liner is inspected
daily. Only Smithco Sweeper-Vacs provide a clean out/inspection port for easy inspection and cleaning.
2. When bare steel is visible at any point in the housing lining, the lining must be replaced. It is expected the liner
will wear and be replaced. It is a vast improvement over competitive units with no liners.
3. Replacement of the liner or the vacuum housing due ti wear is normal and is not covered by warranty.
4. Collection of aerifier cores causes extreme wear on the liner (and if unchecked, on the housing).
5. Caution users that, while Smithco Sweeper-Vacs do an excellent job collecting cores, the lining (and the
housing) will wear quickly in such use.
RUBBERIZED BOOT
The rubberized boot between main unit and sweeper head is subject to wear and damage from debris. Unless
defecetive, replacement of this boot is not covered by warranty.

OPERATION
Before operating this machine, become familiar with all controls and functions of this unit and the tow vehicle.
Alsocomplete all maintenance requirements and read all safety warnings. By knowing both machines thor-
oughly,how it operates and by doing the prescribedmaintenancesteps,you can expect relatively trouble-free
operationfor years to come.
TOWVEHICLE
You will need a 40 HPminimum tow vehicle.
1. Clevis Hitch - You will need a 3/4diameter by 4" pin with some type of lock.
2. Ball Hitch - You will need a 25/16" ball and a locking pin for the coupler.
DAILYCHECKLIST
1. Check engineoillevelin tow vehicle. Add as needed. DO NOTOVERFILL.
2. Tire pressure should be 18 psi (1.3 bar) on Big Vac tires and 20 psi (1.4 bar) on castor wheels.
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-40API Service SJ or higher motor oil.
6. Checkcontrols for smooth, properworkingoperation. Lubricate as needed.
7. Checkand clean all debris from blowerhousing.
ADJUSTMENTOFBELTTENSIONER
There are four maximum belt tensioners on the Big Vac. Two control the tension
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 adjust belt
tensioner, loosen bolt holding tensioner. Bring idler pulley tight to belts and turn
tensioner into belts to 15°. Tighten holder bolt.
CONTROLPANELADJUSTMENTARM
On the right hand side of machine is the
adjustment lock arm, by lifting up you can
