Safety Instructions
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
- When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
- Use safety equipment. Always wear eye protection. Safety equipment, such as a dust mask, non-skid safety shoes, a hard hat, or hearing protection, used for appropriate conditions, will reduce personal injuries.
- Avoid accidental starting. Ensure the switch is in the off position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
- Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts.
Powder Coating Oven
The combination of generous internal volume in a convenient, compact package with big oven features. Selectable upper and lower Heating Elements, and d air Circulation Fan allow optimum control of heat distribution inside the Oven. The Oven Door window presents a convenient view of parts during the critical “flow-out” stage, enabling proper setting of the built-in Timer for the desired cure time. Couple this oven with any of Eastwood’s HotCoat Powder Coating Guns and start coating brackets, housings, and other small to medium-sized parts right in your home shop or garage.
Control Panel & Oven Chamber
- TEMP Control Knob. Rotate to adjust the temperature setting from 150 – 400°F. Turn fully counterclockwise for the OFF setting. Typically, you will be in the 350 – 400°F range for powder coat curing.
- ELEMENT Control Knob. Rotate to set the Heating Elements being used. OFF/Top/ Bottom/Both. Utilizing BOTH Elements is recommended for the best performance.
- POWER Indicator. Illuminates when the Timer is set and able to deliver power to the Elements.
- FAN Knob. Set the Circulation Fan ON or OFF. Turning the Fan ON is recommended for the best heat distribution.
- TIME Knob. Rotate clockwise to turn the Oven ON. Set Timer from 0 – 60 minutes. The Timer must be set for the Oven to power the Elements. Turn the knob fully counterclockwise to turn the Timer OFF. You will hear a bell ding when the Timer disengages.

Operation
- Before loading parts, plan which Rack position works best for your parts. There are three Support Groove levels the Rack may be used with (FIG. 2).
- When curing large or heavy parts, it is best to use the lower Rack level.
- When curing small parts that can easily slip through the Rack, it is best to hang them from the Rack with it in the upper level. Jumbo paperclips bent into an S configuration work well as hooks. Safety wire (Eastwood #43045) and welding wire also EASTWOOD 68076 HOTCOAT BENCHTOP Oven work well to make improvised hangers.
CALIBRATION
- For the most precise cure, Eastwood recommends verifying the Oven Chamber temperature. The following guidelines are best practice:
- Eastwood recommends using an accurate (±5°F) oven thermometer (Eastwood #68139) or type K thermocouple to verify the Oven Chamber temperature.
- Alternatively, you may use an IR thermometer EASTWOOD 68076 HOTCOAT BENCHTOP Oven (Eastwood #31223). Note that various factors can affect the accuracy significantly:
- The emissivity of the material being shot must be known and set in the IR thermometer computer for compensation. Powder coat emissivity is typically 0.91-0.95, but metallic flake will reduce it to around 0.65. Matte black impact sockets with a manganese phosphate coating have an emissivity of approximately 0.92.
- IR thermometers have a distance to spot (D:S) ratio that can often be found on the thermometer or in the instruction manual. This means that as the distance from the part increases, the area being measured is larger. Measurements should be taken within 12” for best accuracy, particularly on smaller parts, such as impact sockets.
- Indirect shooting angles affect results. Measurements should be taken close to perpendicular to the surface.
- Direct line of sight is required. IR thermometers are not capable of taking temperatures through the glass Oven Door. They will only measure the surface of the glass itself.
- Using an object with significant thermal mass is ideal because when you open the door, the part temperature will not drop rapidly. 3/4” (19mm) or larger deep impact sockets are good for this purpose.
- Once satisfied with the steady state temperature EASTWOOD 68076 HOTCOAT BENCHTOP Oven of the Oven, you can mark this point for future reference.
Curing Parts
- To pre-heat the Oven, set the desired temperature. You will typically be at or near the maximum setting for curing. Turn BOTH Heating Elements on unless you have a particular reason to use just one.
- Turn the Circulation Fan ON and set the Timer to about 20 minutes for a pre-heat. The Oven typically takes a minimum of 15 minutes to stabilize at the set temperature. Depending on the ambient air temperature, this time can vary.
- Place the powder-coated part in the Oven. You must wait for the powder to change from its dry solid state to a “glossy” liquid state as the part gets up to temperature.
- Once the entire part has glossed over or “flowed out”, set the Timer to 20 minutes or as specified by the powder manufacturer.
- Open the Oven Door for ventilation or remove and place the part in a location safe for cooling. Allow ample time for the part to cool before handling it.
- Disconnect the Oven from the electrical power source when finished using it.
Storage
- Disconnect the Oven from the electrical power source when not in use.
- Store with the Door closed to prevent dust EASTWOOD 68076 HOTCOAT BENCHTOP Oven and debris accumulation in the Oven Chamber.

Troubleshooting
| PROBLEM | CAUSE | CORRECTION |
| Oven Does Not Reach 400°F | Insufficient Electrical Power to Oven | Verify the Oven is on a dedicated 120 VAC, 15 Amp circuit. If using an extension cord, verify it has a minimum 12AWG wire and does not exceed 50 feet in length. |
| Temp Control Knob Not Set to 400°F | Make sure the TEMP Control Knob is set to 400°F. Follow the instructions in PREPARATION to verify the temperature of the Oven Chamber. | |
| Oven Door Not Closed | Verify the Oven Door is fully closed and is not venting heat. | |
| Low Ambient Temperature | Make sure you are not attempting to operate the Oven in ambient air temperatures below 50°F. The Oven may not be capable of maintaining 400°F in these conditions. | |
| Parts Take Too Long To “Flow Out” | The oven is not Reaching 400°F | Purchase an inexpensive oven thermometer from your local grocery store. Place it on the Rack and set the TEMP Control Knob to 400°F. After a minimum of 15 minutes with the Door closed, observe the temperature on the thermometer. Adjust the TEMP Control Knob to achieve as close to 400°F as possible. |
| Element Control Knob Not Set to Both | Using only the Top or Bottom will prolong the time the Oven takes to achieve 400°F, and it may have difficulty maintaining it. |
| Parts Burnt with Yellow/ Brown Appearance | Cure Time Too Long | Frequently check for flow out before setting the Timer to get the most accurate cure. Heavier parts will take longer to flow out, and lighter parts will not take as long. |
| Cure Temperature Too High | Reduce Oven Chamber temperature. Follow the instructions in PREPARATION to verify the temperature of the Oven Chamber. |
