Thank you for purchasing a product. Read this manual and all other manuals pertaining to the Big Vac carefully as they contain safety, operating, assembly and maintenance instructions. Failure to do so could result in personal injury or equipment damage. Keep manuals in a safe place after operator and maintenance personnel have read them. Right and left sides are from the operator’s seat, facing forward. All machines have a Serial Number and Model Number. Both numbers are needed when ordering parts.
SAFE PRACTICES Introduction 1. It is your responsibility to read this manual and all publications associated with this machine (engine, accessories and attachments). 2. Never allow anyone to operate or service the machine or its attachments without proper training and instructions. Never allow minors to operate any equipment. 3. Learn the proper use of the machine, the location and purpose of all the controls and gauges before you operate the equipment.
1. Always disengage the PTO, shut off engine and remove the keys before leaving the tractor seat. 2. Keep the tractor's master shield in place at all times. 3. Missing or damaged shielding is the main reason for driveline entanglement. Keep All Guards on and in good condition. Check guards frequently. 4. Never step across a rotating powershaft. Always walk around the revolving shaft even if guards are in place. 5. Dress for safety.

MAINTENANCE Before servicing or making adjustments to machine, stop engine on tow vehicle and remove key from ignition. LUBRICATION Use No. 2 General Purpose Lithium Base Grease and lubricate every 100 hours. The Big Vac has 19 to 25 grease fittings, depending on what sweeper head you are using. All bearings are sealed bearings. When inserting grease, be careful not to ruin the seal, if this happens, replace the bearing at once. Be sure to wipe grease fitting clean before injecting grease.
MAINTENANCE (CONTINUED) TIRE PRESSURE Caution must be used when inflating a low tire to recommended pressure. Over inflating can cause tires to explode. Tires on the machine should be 18 psi (1.3 bar), castor wheels should be 20 psi (1.4 bar). Improper inflation will reduce tire life considerably. WHEEL MOUNTING PROCEDURE 1. Turn machine off and remove key. Service 2. Be sure unit is on a level surface. Unhitch from tow vehicle if possible. 3. Block the opposite wheel then the one you are working on. 4.
MAINTENANCE (CONTINUED) HOPPER LIFT SAFETY The Hopper Lift Safety is used to support the ram on the hopper bottom in the extended position so you may service or repair the machine under the hopper. When not in use the Hopper Lift Safety can be stored on the hopper bed frame.

ADJUSTMENTS Service ADJUSTMENT OF BELT TENSIONER 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.
ADJUSTMENTS Service CASTOR WHEELS The castor wheel height spacers are quick spacers meaning they have a slot cut out of them. The castor fork shaft has two flats on it near the bottom. To remove the quick spacers (A) lift up on the castor wheel (C) and remove lynch pin (B). Let the castor wheel come down some, take the quick spacer up and turn it until you feel the flats on the shaft then pull out. This removes the spacers below the castor arm (D), reverse the procedure to add spacers.

TOWING SAFETY WARNINGS 1. Connect safety chains properly EVERY TIME YOU TOW. Cross chains under coupler. Attach securely to the hitch or tow vehicle so they can’t bounce loose. Leave only enough slack to permit full turning. Too much slack may prevent chains from maintaining control if other connections separate. Don’t let chains drag on the road. 2. Make towing light and surge brake connections EVERY TIME YOU TOW, no matter how short the trip. Check operation before getting on the road. 3.
