container. Run the engine for at least 10 minutes after adding a stabilized fuel, to allow the stabilizer to reach the
carburetor. Do not drain the gas tank and carburetor if using stabilizer.
Drain the fuel tank.
Start the engine and let it run until the fuel lines and carburetor are empty and dispose of it in a safe, responsible manner.
Never use engine or carburetor cleaning products in the fuel tank, as permanent damage may occur.
Refill the fuel tank with fresh fuel at the start of next season.
Drain oil (while engine is warm) and replace with clean engine oil (see "ENGINE" in the CUSTOMER RESPONSIBILITIES
section of this manual).
CYLINDER
Remove the sparkplug.
Pour (29 ml) oil through the sparkplug hole into the engine cylinder.
Pull the starter handle slowly a few times to distribute the oil.
Replace with new sparkplug.
OTHER
Do not store petrol from one season to another.
Replace your petrol can if your can starts to rust. Rust and/or dirt in your petrol will cause problems.
If possible, store your vacuum indoors and cover it to give protection from dust and dirt.
Cover your vacuum with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot
breathe which allows condensation to form and will cause your vacuum to rust.
IMPORTANT: NEVER COVER THE MACHINE WHILE ENGINE AND EXHAUST AREAS ARE STILL WARM.
CAUTION:
Never store the vacuum with petrol in the tank and inside a building, where fumes may reach anopen
flame or spark. Allow the engine to cool before storing in any enclosure.
CUSTOMER RESPONSIBILITIES
This section encompasses two general types of maintenance: 1. Preventative Maintenance and 2. General Service.
The first refers to regularly scheduled routine care ofthe sod cutter, such ascleaning and lubrication. The second
provides information on common procedures, such as changing blade, and adjusting the drive belt that are to be performed
as needed.
By following the Inspection Schedule below BEFORE and AFTER each use of the sod cutter, appropriate actions can
be taken to extend the service life of the machine and reduce any costly repairs and unnecessary downtime for the unit.
All service should be performed by trained technicians.
Inspection Schedule
The following list aims offer some basic guidelines to performing a detailed inspection BEFORE and AFTER each use.

GENERAL SERVICEPROCEDURES
General safety procedures
Before performing any service and maintenance procedures, consult these general safety procedures for a safe working
environment.
1. Make sure that both the engine and vacuum are cool prior to any service or maintenance work.
2. Verify that work area is clean and free of any debris, tripping or fire hazards, and other potential sources of danger.
3. Always wear proper safety clothing and equipment for the job. These can and should include eye and ear protection,
gloves, dust mask and any other items that are appropriate for the job and jobsite requirements.
4.Ensure that the technician has tied back or remove anyloose hair, clothing and any other potential hazards and obstructions
5. Disconnect spark plug.
Preventative Maintenance Procedures
Maintaining a regular cleaning and lubrication schedule as well as taking time to perform preventative maintenance
procedures will prolong the service life of the vacuum. The following are guidelines to setting up a regular maintenance
routine for the vacuum.
should read a
nd thoroughly understand all manuals pertaining to the machine to be serviced. Do NOT proceed
with any service and maintenance activity until ALL questions and concerns have been addressed. Please call your
local dealer for technical support and advice.
ALWAYS consult and verify that all local codes and bylaws are followed beforeperforming any service or
maintenance procedures.
Regular cleaning will help extend the service life of the machine.
i. After each use, the vacuum, in particular the blade should be cleaned. Scrape the bottom of gear box and blade to
remove accumulations of leaves or trash.
ii. Clean the engine often, to keep trash from accumulating. A clogged engine runs hotter and shortens engine life.
iii. We do not recommend using a garden hose to clean the leaf vacuum, unless the electrical system, muffler, air filter
and carburetor are properly covered to keep out water. Water in the engine can result in a shorter engine life.
Take care when using a power pressure washer to clean the unit, and avoid damaging any safety or operating instruction
decals. Avoid directly spraying engine. DO NOT USE ANY MACHINE RATED HIGHER THAN 1000 PSI.
iv. B
eware of damaging any warning decals and labels, as well as engine. Limit direct spray on these objects to help
prevent their wear and tear.

MAINTENANCE CONT D...
,
The following are general guidelines for servicing common wear components on the WBLV50 LEAF VACUUM.ALL
MAINTENANCE AND SERVICE WORK MUST BE PERFORMED BY A TRAINED AND EXPERIENCED TECHNICIAN.
Ensure that the work area is clean and free of debris prior to starting any maintenance or service work. Small particles
may become trapped in key components that may lead to serious damage to the machine and cause severe bodily harm
to the operator or technician.

ENGINE
Read the Maintenance section of your engine manual.
CHANGING ENGINE OIL
1. Disconnect sparkplug cable from sparkplug and place the cable where it can not come into contact with sparkplug.
2. Remove engine oil cap; lay aside on a clean surface.
3. Remove the drain plug on the bottom of the engine and drain oil into a suitable container. Grasp starter rope handle
and pull slowly to rotate the crank shaft and remove any oil trapped inside of engine.
4. Reassemble and fasten the drain plug. Wipe off any spilled oil from the engine.
5. Refill engine with the recommended lubricant. See "ADD OIL" in the Operation instructions section of this manual.
6. Reconnect sparkplug cable to sparkplug.
CAUTION: Disconnect sparkplug cable from the sparkplug and place wire where it cannot come into contact with
Sparkplug.
AIR FILTER
Your engine will not run properly and may be damaged by using a dirty air filter. Clean the element after every 25 hours
of operation, or more often if chipper/shredder is used in very dusty or dirty conditions. See the Maintenance section of
your engine manual.
MUFFLER
Inspect the muffler regularly and replace a corroded muffler, as it could create a fire hazard and/or cause damages.
SPARKPLUG
Change your sparkplug each year to make sure your engine starts more easily and runs better.
Set the sparkplug gap at 0.7-0.8 mm.
PERIODIC MAINTENANCE
Periodic maintenance should be performed at the following intervals:

LUBRICATION
Use only high quality detergent oil, which has an API service classification of SF-SJ. Select the oil's SAE viscosity grade
according to your expected operating temperature.
NOTE: Although multi-viscosity oils (5W30,10W30 etc.) improve starting in cold weather, these multi-viscosity oils will
result in increased oil consumption when used above 0 C (32 F). Check your engine oil level more frequently to
avoid possible engine damage from running low on oil. Change the oil after every 25 hours of operation, or at least
once a year if the chipper/shredder is not used for 25 hours inone year. Check the crankcase oil level before starting
the engine and after each five (5) hours of continuous use. Retighten the oil plug securely each time you check the oil level.
