1. INTRODUCTION
1-1. SAFETY PRECAUTIONS
Three safety precautions are described in this instruction manual to avoid risks on human body
during operation. Be sure to read these precautions before using our products.
Each meaning as follows;
DANGER: Indicates a high-risk hazard. If this hazard is not avoided, it may result in severe
WARNING:
CAUTION:
1-2. SAFETY INFORMATION
CAUTION
Do not turn breaker switch ON unless you remove packing materials for transportation inside of
furnace body. Motor unit will automatically rotate for 1 minute to search origin just after turning
breaker ON.
Motor will be broken if you force to rotate without packing material removed.
REMOVE ALL OF CONTENTS INSIDE OF FURNACE AS ABOVE
injury or even death.
Indicates a medium-risk hazard. If this hazard is not avoided, it may resultin
severe.
Indicates a low-risk hazard. If this hazard is not avoided, it may result in a minor or
moderately severe injury. It also indicates a potentially hazardous situation. If it is
not avoided, the product or items in its immediate environment may suer.
5
RBF 32/21 Instruction Manual SKU: 77-021

DANGER
1. Since this product generates very high temperature (more than 900 degrees Celsius), always
pay attention not to suer burns. Do not allow unskilled or untrained person to operate this
product.
Person who does not pay attention is highly possible to suer serious burns.
2. This product is electric furnace designed for lost-wax casting. However, depending upon
material, it may be possible to use this product for burning resins (such as material for Rapid
Prototyping). If you need to use resins, examine properties of the resins beforehand thoroughly
and carefully, and check for safety because various resin materials are distributed on the market.
There are some resins which react aggressively being drained burning and splashing which may
bring a re.
3. Do not use or stock any inammable gas, inammable volatile liquid, or organic solvent near
this product or in the room where it is installed.
They may catch re and spread.
4. When incomplete combustion gas of wax is generated, do not open the door. If you open the
door at the time, the gas inside of furnace may catch re and explode which can bring a re.
5. During or just after burnout, surrounding parts of the furnace opening are
heated to very high temperature, so take utmost care not to burn your
hands etc. Stay away from RBF unless you wear gloves, goggles and other safety equipment.
6. Before opening the door, ensure for safety that there is nothing in the
door's way. Operator and third person may cause serious injury and burn.
7. Do not leave the door of the furnace open when this product is not used. It
may catch re and explode which can bring a re.
8. Always keep clean inside of the furnace. Investment residue or dusts on turntable or wax drain
orice etc. may cause clogging and prevent wax from draining out of furnace. As a result, a large
amount of incomplete combustion gas is discharged. It may catch re and spread.
9. Do not pile up asks. If asks fall down, the inner wall of the furnace may be damaged. Further,
if they come into contact with the heater wires, an accident such as short-circuit may be caused.
6
RBF 32/21 Instruction Manual SKU: 77-021

CAUTION
1. Periodically, check and clean the rotation driving parts. Remove wax on the bearing system.
Rotation can be suspended by wax and rust sticking which lead over load at each driving part.
2. Do not try to cool inside of the furnace forcibly and very rapidly using a fan. Particularly, if
forced at high temperature, the door frame material may be cracked or deformed. Heat insulation
eect can be decreased. There is a serious risk of injury and burns on body by breaking and
falling down of adiabatic blocks and panels.
3. When burning out a large number of asks in one batch, take ample time for each step of
burnout cycle. If not, too much harmful incomplete combustion gas can be generated and will be
overowed from afterburner. It also may aect burnout result.
4. Always use the wax collection container.
A deep container is recommended because drained wax will not splash around. Temperature of
drained wax is very hot like over 200 degrees Celsius which may catch re and spread. 5. Always
be sure to check setting temperature of overheat protection function beforehand, and change
LIMIT if necessary to proper value for the purpose.
1-3. PASSWORD
1-3-1. KIND OF PASSWORD
Three kinds of password are prepared for this product as follows.
1) Start password (at installation)
