... have you been trained
The law requires that personnel using this type of equipment in
the workplace must be competent and qualified to do so.
Training is available at HSS Training

Never push the equipment beyond its design limits.
If it
will not do what you want with reasonable ease and speed,
assume you have the wrong equipment for the job. Contact
HSS Hire for advice.
Keep the engine upright at all times.
If it should get
tipped over, mop up any oil or fuel spillage and contact HSS
Hire for advice. Regularly check the fuel level and top up as
required using the correct fuel: lead free petrol.
Check the engine oil level daily.
Top up as required.
Keep the equipment clean
- you will find this less of a
chore if you clean it regularly, rather than wait until the end
of the hire period.
When not in use, store the equipment somewhere
clean, dry and secure.
EQUIPMENT CARE
FINISHING OFF
Turn the engine switch to the OFF position and close the
fuel tap.
Let engine cool for at least five minutes before storing.
Give the unit a final clean up ready for return, to HSS Hire.
Once the engine has built up speed, pivot the grinder
toward the side of the stump, with a fairly light touch
feed straight into the stump. As soon as you feed in,
start to swing to the side until you feel the wheel drop
off the edge of the stump. Change direction and swing
back the other way until you feel it reach the other edge
of the stump. As you swing to the side listen to the
engine. Provide enough feed to give it a moderate load.
If you hear any belt or clutch squealing you are pushing
too hard. If you can’t swing it to the side, raise the
grinder up.
You can cut roots off by plunging straight through them.
When grinding larger stumps,
chips may begin to build up
under the wheels.
Release brake and pull machine
towards you
so that the "chip pile"
is directly under the cutting wheel.
On these larger stumps, do not allow grinder wheels to
drop into stump hole. If a hole is in the way of your
progress, fill it with chips or change position.
When finished, stop the machine.
Pull machine away from stump, and rake chips away
from stump.
STOPPING ENGINE
While holding blade off ground,
release the operator
presence bar.
The engine will stop.
Wait until the blade
completely stops. Lower the blade
so it is resting against
the ground.
Make sure brake is set before leaving the controls,
particularly if you are on an incline.
Turn engine switch to OFF position.
Allow the engine to cool for at least 5 minutes before
releasing brake and moving for storage or transporting.
A hot engine can be a fire hazard.
