Danger of fire and burns

During operation, the stove becomes hot and it must therefore only be operated under supervision.
Long heating times and high heating temperatures can lead to overheating of the stove, which in
turn may cause fire.
When placing pcbs into the oven or removing them, wear suitable gloves or use fireproof equip -
ment.
If the stove generates too much smoke, pull the plug and close the door. That stifles the flames.
Do not place flammable materials in the vicinity or on the reflow oven.
Do not block the ventilation grilles.
Do not touch the cover of the stove, it can be very hot and you risk severe skin burns.
Do not place flammable, explosive or other hazardous substances near the reflow oven. Do not dry
objects that emit flammable and explosive gases! 

Never set a temperature higher than 300 ° C!  

The stove is not designed for that and could be

damaged. We exclude a guarantee for this! 

Exhaust

Use the oven only in well-ventilated areas. Follow the safety rules of the solder paste and adhesive
suppliers. During the soldering process gases can arise. These gases may endanger your health.
We recommend the use of a hood or an alternative extractor option!

1. Check the proper function of the stove using the following checklist:
2. Check the drawer. The drawer must not be kinked or damaged.  Do not use the oven if

something is stuck between the lock and the ceiling. If the drawer is damaged, do not use
the oven

3. Check the seal for damage
4. Check if the oven room is free of dents.
5. Check the power cord, plug and socket for damage. 

Maintenance

Clean the oven regularly. A dirty stove can lead to dangerous situations.
Do not insert wire or other foreign objects into the air inlet and outlet to avoid burns or damage to
ventilation and heat.
Do not wash the machine directly with water in order not to affect the insulation performance of the
machine.
