Safety Instructions
WARNING! Read and understand all instructions.
Failure to follow all instructions listed below, may result in electric shock, fire and/or
serious personal injury. SAVE THESE INSTRUCTIONS.
Work Area Safety
1. Keep your work area clean and well lit. Cluttered floors and dark areas invite accidents.
2. Do not operate equipment in explosive environments, such as in the presence of -
flammable liquids, gases or dust. Grinding can create sparks which may ignite the dust or
fumes.
3. Keep bystanders, children, and visitors away while operating equipment. Distractions can
cause you to lose control.
Electrical Safety
1. Do not abuse the cord. Never use the cord to pull the equipment or pull the plug from
an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged
cords immediately. Damaged cords increase the risk of electric shock.
2. Make sure cord is clear of wheels and cutting discs. Do not wrap cord around your arm
or wrist. If control of equipment is lost, cord may become wrapped around you and
cause personal injury.
3. When operating equipment outside, use an outdoor extension cord marked "W-A" or
"W". These cords are rated for outdoor use and reduce the risk of electric shock.
4. Avoid accidental starting. Be sure stop button is depressed before plugging in. Starting
equipment with your finger on the start buttons or plugging in equipment that has the
buttons depressed invites accidents.
5. USE THE PROPER EXTENSION CORD. Make sure your extension cord is in good
condition. When using an extension cord, be sure to use one heavy enough to carry the
current your product will draw. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
For the RXL1000 use 10-gauge cord or larger.

WARNING: Misuse or failure to follow the safety rules stated in this instruction
manual may cause serious personal injury. SAVE THESE INSTRUCTIONS.
Operating the Grinder
The machine is outfitted with a Variable Frequency Drive (VFD) enabling the user to select the
desired operating speed.
The equipment can operate on either 50 Hz or 60 Hz frequencies.
The VFD will automatically adjust for phase or frequency input which will raise or lower head
speed on the machine.
VFD features:
 Under voltage protection - Over current protection
 60Hz and 50Hz capability (international)
 110V
 Soft start

RXL1000 Users Manual

 Speed display
 Load display
 Current limiting
NOTE: LED DISPLAY – Shows PAD speed when machine is running and says “STOP”
when plugged in but not running.
Prior to using the grinder
1. Inspect the grinder to make sure all bolts are tight, and that tools are properly mounted
2. Check that the plug is properly connected to the extension cord and inspect the cord for
wear and tear.
3. Make sure that speed dial is turned to its lowest setting
WARNING: This will prevent unexpected high speed start up which could cause
some tools to eject or cause undesirable marks to the surface being finished.
4. Plug the machine in – the VFD LED should read “STOP”
Starting the grinder
DO NOT LIFT THE EQUIPMENT OFF THE GROUND WHILE STARTING!
Doing so can cause the tools to release from the equipment and cause damage to
the surface being finished and harm to the user!
1. With the machine in an upright position, set the articulating handle to the desired
position.
2. Check that speed dial is set to slowest speed.
3. Plug the power cable in, making sure that extension cord is not tangled or wrapped
around any obstacles.
4. Ensure that the VFD LED reads “STOP”
5. Apply downward pressure on the handle to alleviate some pressure on the tools and
press the GREEN start button. (If you want the machine to run in reverse you can push
the yellow start button.
NOTE: Always use the equipment in the forward rotation mode (green button) unless
reverse rotation is needed. This will ensure consistent tool wear.
The use of the equipment in the reverse rotation is only needed when surface being finished
is uneven and causes the equipment to pull in an undesired direction or when the tooling is
glazed and needs to be re-dressed.
6. Once the equipment is started, gently release the downward pressure and start grinding.

RXL1000 Users Manual

NOTE: The equipment is designed to rotate the tooling in either the forward direction
(green button) or reverse direction (yellow button) depending on operating needs.
Adjusting the speed
1. Use the knob, located on the right side of the handle control box to adjust speed of
equipment.
Stopping the equipment
1. To stop the equipment, turn speed control knob to the slowest setting and,
2. push the red stop button on the face of the handle
Adjusting the handle
1. Make sure machine is unplugged
2. Pull the hand latch or step on foot latch on the handle and move handle up or down to
the desired position.
Avoid stepping on or tangling handle control cable when adjusting the handle position.
Make sure that the latch clicks in place when the desired position is achieved.
WARNING: Failure to check for positive handle latch engagement could result in
damage to the equipment or injury to the user as the handle could release
unexpectedly when the machine is being operated or tilted back!
Using the biased weight kit
The Rhino line of equipment was designed to be used with our biased weight kit, which
allows our machines to be loaded with weights to increase point pressure for very hard
floors and to rapidly expose aggregate.
Our unique patented biased weight system uses standard Olympic weight plates,
allowing placement on either side of the machine to increase pressure when grinding
edges with slab curl and high and low spots.
Weights can also be placed on the handle to alleviate pressure and weight from the
machine, enabling the Rhino to be easily and effectively used for soft & rained out slabs.
For best results and to increase production we highly recommend utilizing weights with
your Rhino grinder.
