INTRODUCTION 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.
SAFE PRACTICES 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.
PTO SAFETY WARNINGS 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.
MAINTENANCE Before servicing or making adjustments to machine, stop engine on tow vehicle and remove key from ignition. Use all procedures and parts prescribed by the manufacturer's. Read the engine manual before operation. LUBRICATION Use No. 2 General Purpose Lithium Base Grease and lubricate DAILY. The Big Vac has 19 to 25 grease fit- tings, depending on what sweeper head you are using.

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.
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.
SERVICE CHART Before servicing or making adjustments to the machine, stop engine, set park break, block wheels and remove key from ignition. Follow all procedures and ONLY use parts prescribed by the manufacturer. Read the engine manual before maintenance. ¤£ Engine O il Engine O il Filter Engine for Leaks and Loos e Parts ‡...

ADJUSTMENTS 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.
ADJUSTMENTS 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 re- move the quick spacers (A) lift up on the castor wheel (C) and remove lynch pin (B).

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.
