KNOWING THE G41
The G41 has 4 hydraulic wheel motors that allow forward, reverse and turning without relying on chains that stretch and can
break. These motors are controlled by two levers. Two control levers are also provided for lift of the loader arms and tilt of
the attachment plate. The control levers are sensitive and require some practice to enjoy the manoeuvrability they will
provide to the operator.
Attachments are controlled by the accessory control lever, this is a push to engage and pull to engage lever with detent. The
center position is the “OFF” position. This allows for clockwise and counter clockwise rotation of a hydraulic motor or in
and out of a hydraulic cylinder. (Keep from using the detent if operating an accessory with a cylinder).
The G41 also provides the ability to decide how much hydraulic oil flow the operator wants to direct to the accessory by
adjusting the flow control lever.

THE CONTROLS
1. Control lever for the left side travel motors
Pushing forward on this lever turns the left wheels forward
Pulling back on this lever turns the left wheels backward
2. Control lever for the right side travel motors
Pushing forward on this lever turns the right wheels forward
Pulling back on this lever turns the right wheels backward
3. Control lever for loader arms
Pulling on this lever lifts the loader arms
Pushing on this lever lowers the loader arms
If you push on this lever past its detent point it will lock and activate the float function which allows the loader arms to float
and allows the bucket or other attachments to follow the contours of the ground.
4. Control lever for the tilt function
Pushing on this lever tilts the attachment plate forward.
Pulling on this lever tilts the attachment plate backward.
5. Accessory control lever
This lever will direct oil flow to the accessory. The operator can either push or pull on the lever to send oil
flow to a hydraulic cylinder. Or if the accessory has a hydraulic motor, the lever can be set in its forward or
reverse detent position.
Make sure to bring the lever back to the “OFF” or center position to stop flow to the accessory and to relieve
pressure.
NOTE: The engine may be hard to turn over when starting if this control lever (#5) is left in a detent
position.
6. Flow control lever
This lever will provide more or less flow to the accessory valve allowing the operator to choose the flow at
which he wants to operate an attachment without having to lower or increase engine RPM.
It is also a good idea to reduce flow before engaging and disengaging the accessory lever to minimize shock to
the accessory motor.
NOTE: When an accessory is not being used, it is best to leave this lever (#6) in the “OFF” position.

WORKING AREA
It is important that you first walk the area that you are going to work in with the G41.
-Look for loose or soft soil, wet, damp or muddy land, sandy or icy conditions are all potential hazards when operating
a mini loader.
-Holes, drop-offs, ditches, slippery surfaces, culverts, unstable surfaces, hillsides, large rocks, trees are all causes for
concern.
-Evaluate the situation before proceeding with the task at hand. Do not proceed if the hazards can not be corrected or
avoided.
-Make sure to have the area marked for buried lines.
-Consult local utility service providers (gas, electric, cable, water, telephone) before any digging is performed.
OPERATING PRECAUTIONS
-Start by planning your work
-Inspect the G41, check for leaks, broken or loose parts, check oil levels (hydraulic and engine), check and refill fuel
tank.
-Check wheel motor woodruff keys daily to ensure that the wheel hub is solidly attached to the wheel motor.
Using the machine with a broken woodruff key will damage the hub and wheel motor.
-Operate all controls smoothly and slowly and never stop abruptly, avoid brisk movements. This will make your work
safer and more comfortable.
-Always keep a firm grip on the handle bar as the machine moves to keep from loosing balance and injuring yourself.
-Always look in the direction you are going, turn and or reverse at a reduced speed. Do not make sharp turns at speed
and try to come to a stop smoothly.
-Stop operating the machine if someone wanders to close.
-Never exceed the rated capacity on the G41 and or its attachments. Understand that different attachments will change
the way the G41 acts and reacts.
-Travel with the bucket or attachment as close to the ground as possible, traveling with raised loader arms will make
the machine unstable.
-Try to avoid working on slopes, but if necessary use extreme caution and travel at lower speeds.
-Do not travel across slopes.
-Do not park on slopes.
-If you have to work on a slope, travel straight up or down making sure the heavy end of the machine is always
pointing up the slope.
-On an empty or unloaded machine the operator platform is the heavy end.
-On a loaded machine or with a heavy attachment, the front is the heavy end.
-Load, unload and turn on flat level ground. Do not travel or turn with loader arms up.
-Operate only from the operator’s platform; always keep hands on handle bar and controls.
-Keep the bucket level when raising loader arms to prevent material or debris from falling from bucket.
