Introduction
SETUP
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 13 grease fittings. All bearings are
sealed bearings. When inserting grease,
be careful not to ruin the seal, if this hap-
pens, replace the bearing at once. Be
sure to wipe grease fitting clean before
injecting grease. Give only one or two
pumps of grease at each lubrication.
REF# LOCATION
1 One on all four castor
wheels.
2 Two on the fan shaft.
3 One on each mounted bearing for reel shaft.
4 One on all four castor wheel mount brackets.
5 One on the jack stand.
HYDRAULIC OIL
1. Use SAE 10W-40 API Service SJ or higher motor oil.
2. For proper warranty, change oil every 500 hours or annually, which ever is first and change the filter after
the first 20 hours, then at 100 hours, then every 250 hours thereafter.
3. Inspect hydraulic lines for damage or leaks. Never use hands to inspect leaks.
4. 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.
5. After changing oil and/or filter, operate the machine for a few minutes. Check oil level and for leaks.
6. Always use caution when filling hydraulic oil tank or checking level to keep system free of contaminants.
Check and service more frequently when operating in extremely cold, hot or dusty conditions.
7. If natural color of fluid is now black or smells burnt, it is possible that an overheating problem exists.
8. If fluid becomes milky, water contamination may be a problem.
9. If either of the above conditions happen, change oil and filter immediately after fluid is cool and find cause.
Take fluid level readings when system is cold.
10. In extreme temperatures you can use straight weight oil. We recommend SAE 30W API Service SJ or
higher when hot (above 90°F (33°C)) and SAE 10W API Service SJ or higher when cold (below 32°F (0°C))
ambient temperature. Use either motor oil or hydraulic oil, but do not mix.
11. Oil being added to the system must be the same as what is already in the tank. Mark tank fill area as to
which type you put in.
