Installation, Operation, Use and Care
SAVE THESE INSTRUCTIONS
GENERAL
The mixer bowl scraper attachment continually scrapes the sides of the bowl as the agitator turns. Material around the side and bottom of the bowl is constantly re-introduced into the mixture. Manual scraping is not needed when using the bowl scraper. The bowl scraper is used when mixing batters or creaming. The bowl scraper is not intended for mixing dough products. The bowl scraper is used only with stainless steel bowls.

INSTALL BOWL SCRAPER LABEL ON MIXER HEAD — ALL MODELS
Prepare a clean dry place on the mixer head where the Bowl Scraper label (included with kit) can be seen by the operator. Peel off the backing paper and apply the label (Fig. 12).
Diagram Description (Fig. 12): Shows a mixer head (H600 model depicted) with the bowl scraper label being applied.
OPERATION
❗ WARNING: MOVING BEATER AND SCRAPER IN BOWL. KEEP HANDS, CLOTHING AND UTENSILS OUT WHILE IN OPERATION.
Lubricate the bowl surface with vegetable oil or shortening, especially in the area above the product where the sleeve might rub against the bare surface of the bowl. The bowl scraper rotates clockwise as you look down into the bowl. Use speeds one and two only. Do not use bowl splash cover or bowl extension ring.
Products which can be mixed while using the bowl scraper are:
- Mashed Potatoes
- Waffle/Hot Cake Batter
- Cake Batter
- Sugar Cookies
- Icing
- Creaming Shortening/Sugar
- Creaming Eggs/Sugar
- Mayonnaise
Bowl Scraper should be used with wire whip or flat beater agitators only. Stainless steel bowls must be used.
- Lower the empty bowl. Rotate Wire Cage Assembly on Bowl Guard to the rear (if equipped). Insert arm into bracket; lift arm up until engaged (Fig. 13). The knob on the mounting bracket will snap into place while lifting the arm. Attach beater to mixer shaft.
- Raise bowl to operating position. Add ingredients. If mixer is equipped with Bowl Guard, return Wire Cage Assembly to the front-center position. Run mixer normally.
? NOTICE: Never raise a bowl of stiff product (i.e., cream cheese, shortening, unmashed potatoes) with the scraper arm engaged in the mounting bracket. The scraper arm can be permanently bent and become damaged by rotating beaters (Fig. 14).
Hold the start button to run the agitator while the bowl is being raised; or, load the bowl after it is raised.
Diagram Description (Fig. 13): Shows a hand inserting the scraper arm into its mounting bracket on the mixer.
Diagram Description (Fig. 14): Illustrates the difference between a normal arm and a bent arm, with a warning that heavy product can bend the arm.
Removing the Scraper Arm
- To remove scraper arm after using: Lower the bowl. Open the Wire Cage Assembly on the Bowl Guard (if equipped). Pull the black knob out. Lower the scraper arm (Fig. 15). If needed, remove the bowl, contents, and beater.
Diagram Description (Fig. 15): Shows a hand pulling a knob to lower the scraper arm from its bracket.
Diagram Description (Fig. 16): Shows the urethane sleeve being tapped against a table to aid its removal from the arm.
Cleaning
To remove the scraper arm from the planetary bracket, lower the bowl, pull out on the knob and lower the arm (Fig. 15). Remove the urethane sleeve from the arm. Tapping the sleeve against a table will aid removal (Fig. 16).
Clean both parts in a sink with warm water and detergent solution. Do not wash urethane sleeve in a dishwasher or use water above 110°F. Rinse with clear water and air dry.
Do NOT use harsh chemicals (i.e., bleach) to clean the sleeve as this will degrade the urethane.
Slide sleeve onto arm so bevel is the leading edge; use a little water as a lubricant. Refer to Fig. 11 for proper sleeve position. Be sure the top of the arm is clean before reassembly into the scraper mounting bracket.
Clean bracket as you would the exterior of the mixer. Wipe with a cloth moistened with warm water and detergent solution. Dry with a clean dry cloth before installing scraper.
MAINTENANCE
Lubricate the top of the scraper arm occasionally with a little Chevron Poly FM #2 (supplied). This will lubricate the mechanism. Keep the end of the scraper arm clean when you insert it in the bracket slot.
The bracket cover can be removed (4 screws) for periodic cleaning and application of Chevron Poly FM #2 grease.
TROUBLESHOOTING
| Symptom | Remedy |
|---|---|
| Scraper grabbing bowl. | Lubricate bowl surface with vegetable oil or shortening. |
| Bevel edge not leading. | Remove arm and reinstall urethane scraper. |
| Beater/Bowl clearance excessive. | Hobart Service can adjust the Beater/Bowl clearance so the scraper fits the side of the bowl. |
