OPERATIONS AND SAFETY MANUAL
INCLUDING PARTS CATALOG
READ AND FAMILIARIZE YOURSELF WITH THIS MANUAL BEFORE OPERATING THIS MACHINE
FOLLOW INSTRUCTIONS DURING USE
INTRODUCTION
YOUR R900 ROUND - O - MATIC DOUGH ROUNDER HAS BEEN BUILT WITH THE BUSY BAKER IN MIND.
IT’S VERSATILITY AND SIMPLICITY ARE UNMATCHED IN THE INDUSTRY. PRODUCTION DEPENDS ON
THE DESIRED DOUGH BALL SIZE AND HOW FAST THE DIVIDED DOUGH PIECES ARE DROPPED INTO
THE FUNNEL. SMALL PIECES CAN BE FED APPROXIMATELY TWO PER SECOND, WHEREAS LARGER
DOUGH PIECES (UP TO 2 lbs.) MUST BE FED AT A LESSER RATE. GETTING THE FEEL OF THE MACHINE
WILL BEST DETERMINE JUST WHAT THE FEED RATE SHOULD BE FOR ANY CERTAIN DOUGH BALL
SIZE. NO ADJUSTMENTS ARE NECESSARY WHEN CHANGING THE SIZE OF YOUR DOUGH PIECE, IT
WILL AUTOMATICALLY BE ROUNDED INTO A TIGHT, SMOOTH BALL, WITH NO MORE EFFORT THAN IT
TAKES TO DROP THEM INTO THE FUNNEL.
CAUTION:
ALL OPERATORS MUST BE FULLY TRAINED AND INSTRUCTED IN SAFETY PROCEDURES
BEFORE BEGINNING PRODUCTION.
SPECIFICATIONS
INSTALLATION INSTRUCTIONS
LOCATION:
SELECT LOCATION CAREFULLY. THE AREA SHOULD PROVIDE THE OPERATOR WITH ENOUGH SPACE
TO USE THE EQUIPMENT IN A SAFE MANNER. THE FLOOR AREA SELECTED SHOULD BE A FLAT
SURFACE AND EASY TO CLEAN AND SHOULD BE FREE OF OIL, GREASE, ECT. AVOID AREAS WHERE
BYSTANDERS AND CUSTOMERS MAY BE PRESENT.
CAUTION
PROPER UNIT INSTALLATION IS NECESSARY FOR SAFE AND EFFICIENT OPERATION. PROPER
INSTALLATION ALSO HELPS PROTECT THE UNIT FROM DAMAGE AND MAKES SERVICE EASIER.
