ML-134499

Overview

Hobart ML-134499 is the model number for the ES20 mixer — a 20-litre planetary mixer in Hobart's Ecomax line of 10 and 20 litre planetary mixers. Hobart's own spare parts list, Form 43208 (October 2009), covers the ES20 under two model numbers: ML-134499, the 115 V build, and ML-141009, the 240 V build of the same machine. The smaller ES10 models, ML-134376 and ML-134377, appear in the same manual family as related models.

Form 43208 breaks the ES20 into ten illustrated sections: control panel (PL-59222), electrical components (PL-59224), attachment hub, base and pedestal, bowl support, transmission case and motor (PL-59232), transmission (PL-59234), bowl guard (PL-59236), agitators and accessories, and wiring harnesses. PartHubz provides this manual for ML-134499 owners and supplies the replacement parts it lists, with support at 833-700-8006 or [email protected].

Key Features

Installation & Requirements

Form 43208 is a parts document, so it does not publish clearance or ventilation figures for the ES20. What it does establish is the electrical identity of ML-134499: this model number carries the 115 V controller and the 120 VAC 2-pole relay. The 240 V controller (00-937124-00002) and 240 VAC relay (00-087714-042-3) listed alongside them belong to ML-141009, so replacement electrical components must be ordered to match the voltage of the machine in front of you.

The manual also states plainly: if service is needed on this equipment, contact your local Hobart Service Office.

Operation

The ES20 is a planetary mixer: the agitator spins on its own axis while travelling around the bowl, the motion that gives the design its name. On ML-134499, the Delta controller (00-937124-00001) on the control panel and the 2-pole 120 VAC relay (00-087714-042-1) handle the machine's control side.

Cleaning & Maintenance

The transmission case is closed by cover 00-917083-00002, held by 5/16 x 7/8 hex socket cap screws (SC-062-81), with retainer 00-937158 at the top bearing. For anything beyond parts replacement, the manual's direction is straightforward: contact your local Hobart Service Office.

Applications

A 20-litre planetary mixer fits the daily production rhythm of bakeries, pizzerias, restaurants, hotel kitchens, institutional cafeterias and test kitchens — anywhere batches of dough, batter, icing or whipped products are mixed in 20-litre volumes. The attachment hub extends the machine beyond the agitators and accessories listed in the manual, letting the same motor drive hub-mounted accessories.

Parts stocking is simpler than it looks: several ES20 components — the BB-005-34 ball bearing, the 00-023482 oil seal, the 46T bevel gear and the hub thumb screw — are shared with other Hobart mixers such as the A200, HL120, HL200, HL200C, HL300, HL400, ES300 and ML-141009, so the same part numbers serve multiple machines in a mixed fleet.
