themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.
If you need to replace a part, use genuine Stoelting
parts with the correct part number or an equivalent
part. We strongly recommend that you do not use
replacement parts of inferior quality.

SHIPMENT
2.1 SHIPMENT AND TRANSIT
The LIL' SHAVER® has been completely assembled,
operated and inspected at the factory. Upon arrival at the
final destination, the ice shaver must be checked for any
damage that may have occurred during transit. THE
CARRIER IS RESPONSIBLE FOR ALL DAMAGE IN
TRANSIT,WHETHER VISIBLE OR CONCEALED. Do not
pay the freight bill until you have checked the equipment.
Have the carrier note any visible damage on freight bill. If
concealed damage and/or shortages are found later, advise the carrier inspector within ten days and request
inspection. You must make claim for damages and/or
shortages in shipment with the carrier. STOELTING, INC.,
CANNOT MAKE ANY CLAIMS AGAINST THE CARRIER.
2.2 INSTALLATION
A. Unbox the Lil’ Shaver
B. Place on a level, solid surface.
C. Adjust the rubber feet until the shaver is level and
resting solidly on all four feet. (Feet can be placed in
alternate locations to match various counter depths).
D. Connect the separate drain hose to the drain, and direct
the hose to a sink, floor drain or container. Liquid must
not cover the hose end or the unit will not drain properly.
(Figure 1)
E. Plug the 115 volt 15 amp cord plug into a dedicated
circuit. We do not recommend using an extension cord,
but if it is necessary to use one, it must be a number 12
gauge or heavier wire with a ground.
WARNING
DO NOT USE A GROUNDED ADAPTER PLUG OR
ALTER THE ELECTRICAL CORD IN ANY WAY.
FAILURE TO HEED THE WARNING COULD
CAUSE DAMAGE TO THE MACHINE OR PERSONAL INJURY.

OPERATOR INSTRUCTIONS
3.1 OPERATORS SAFTEY PRECAUTIONS
Safe operation is no accident; observe these rules:
A. Know the equipment. Read and understand the operat-
ing instructions.
B. Notice all warning labels on the equipment.
C. Wear proper clothing. Avoid loose-fitting garments, and
remove watches, rings or jewelry which could cause a
serious accident.
D. Maintain a clean work area. Avoid accidents by clean
ing up the area and keeping it clean.
E. Stay alert at all times. Know which switch, push button
or control you are about to use, and what effect it is
going to have.
F. Disconnect electrical cord for maintenance. Never at-
tempt to repair or perform maintenance on the unit until
the main electrical power has been disconnected.
G. Do not operate under unsafe operating conditions.
Never operate the machine if unusual or excessive
vibration occurs.
H. Do not operate the unit without the hopper cover and
hopper in place and intact. (Figure 2)
3.2 LIL’ SHAVER AND BLENDER CONTROLS
Before operating it is required the operator know the
function of each operation control. Refer to Figure 3 for
location of the operating controls on the machine.

B. Blend Time Adjuster. To increase blend time (fine ice)
turn adjuster clockwise. To decrease blend time turn
adjuster counter-clockwise.
NOTE
Use a small screwdriver to adjust.
C. Blend Start Switch. When activated, the start switch
will blend the drink for the pre-set time.
A. The POWER ON/OFF switch. When the POWER ON/
OFF switch is placed in the OFF position, the machine
will not run. When the switch is placed in the ON
position the shaver and blender can be operated by
activating the appropriate switch.

D. BLEND ONLY Switch when activated, the blender drive
will run until the switch is released.
E. HIGH SPEED/LOW SPEED Switch (models S100/
S500 only). When in the LOW SPEED position, the
blender drive operates at the lower speed when the
BLEND ONLY switch is activated. When in the HIGH
SPEED position, the blender drive will operate at the
higher speed when the BLEND ONLY switch is activated.
F. NUMBER OF DRINKS ROTARY Switch (models S100/
S500 series only).The NUMBER OF DRINKS switch
operates a timer. When the desired number of drinks
has been selected and the START switch activated, the
machine will shave enough ice for that number of drinks,
then stop.
WARNING
USE CAUTION WHEN ACCESSING THE ICE
SHAVING AREA. THE ICE SHAVING BLADE IS
EXTREMELY SHARP. CONTACT WITH THIS
BLADE COULD CAUSE INJURY .
B. Spray ice hopper and shaving area with an approved
cleaner/sanitizer.
C. Wash hopper cover in warm soapy water, rinse, then
sanitize and let dry.
CAUTION
DO NOT PUT ANY P ARTS THROUGH THE DISHWASHER. THESE PARTS ARE NOT DISHWASHER SAFE AND DAMAGE WILL OCCUR.
G. SHAVE TIME ADJUSTER to increase shave time
(more ice) turn adjuster clockwise. To decrease shave
time turn adjuster counter-clockwise.
NOTE
USE A SMALL SCREWDRIVER TO ADJUST .
H. Shave START Switch (models S100/S500 series only).
When activated, the START switch will shave ice for the
number of drinks selected, then stop.
I. SHAVE ONLY Switch. When the SHAVE ONLY switch
is activated, the machine will shave ice as long as the
switch is depressed. When released, it will stop.
3.3 Cleaning and Sanitizing
It is important to keep your LIL' SHAVER® clean and
sanitary. To properly clean and sanitize, follow the instructions below.
A. Remove ice from hopper by pressing the SHAVE ONLY
switch and dispensing into a container.
D. Disassemble blender following the steps outlined be
low.
1.Remove cover center knob (if used) by turning counter-
clockwise.
2.Remove blade assembly from bowl by turning counter-
clockwise viewed from driven end.
WARNING
NEVER GRASP THE BLADE ASSEMBL Y BY THE
CUTTING BLADES. THE BLADES ARE EXTREMEL Y SHARP AND COULD CAUSE INJUR Y
IF HANDLED IN A CARELESS MANNER.
3.Remove rubber gasket.
4.Clean all parts in warm soapy water, rinse, then
sanitize and let air dry.
5.Assemble all parts in reverse order.

SECTION 4
ADJUSTMENTS
4.1 Dispense Rate
The rate of ice shaving can be adjusted by raising or
lowering the shaving blade. The adjusting screw is accessed from just behind the POWER ON/OFF switch.
Counter clockwise rotation of the adjusting knob gives a
faster dispense rate (more ice shaved in the same time.)
Make small (1/8 turn) changes in the adjusting screw until
the desired rate is achieved. (Figure 4)
4.2 Shaver Motor Reset
The machine’s shaver motor is equipped with an overload
devise to protect the motor and shaver. Manually reset this
protector by pulling the reset lever down. (Figure 4)

potentiometers, and time delay relays. The electrical controls along with an adjustable ice shaving blade allow the
operator to not only adjust the amount of ice shaved but
also the ice shaving size.
To gain access to the electrical controls perform the following procedures:
W ARNING
DISCONNECT SHAVER FROM THE SOURCE OF
ELECTRICAL SUPPL Y BEFORE SER VICING .
