SATER service centre has been repairing Bosch Professional and Bosch DIY (green line) power tools in Riga since 1993 — over 30 years of hands-on experience at the same address: Silmaču iela 6, LV-1012. Our history traces back to workshop No. 2 of the Soviet-era "Elektrons" factory, and over the decades we have built deep expertise across the full Bosch power tool range: GBH series rotary hammers (GBH 2-26 DRE, GBH 2-28 F, GBH 5-40 DCE), GSR cordless drill/drivers and GSB impact drills (GSR 18V-60 C, GSB 18V-55), GWS series angle grinders (GWS 22-230, GWS 13-125 CIE), GKS circular saws, GST jigsaws, as well as GSA reciprocating saws and GOP multi-tools. We repair at the component level — replacing carbon brushes, rotors and stators, rebuilding gearboxes, re-soldering BMS controller transistors in battery packs, and replacing trigger switches and speed controllers. Before starting any work, the customer receives a clear cost estimate. If the repair is not economically viable, we say so directly and return the tool with no obligation. All completed work carries a 3-month warranty; battery cell replacements carry a 6-month warranty. Over 186 Google reviews with a 4.3-star average confirm the quality of our service. Bring your Bosch power tool to Silmaču iela 6 — we will sort it out.

Common problems we fix
- Carbon brushes worn out — sparking, power loss, or complete motor stall
- Rotary hammer gearbox hums but delivers no impact — intermediate shaft wear, barrel bearing failure, or lubricant leak
- Battery won't hold charge or won't charge at all — Li-Ion cell degradation, BMS controller failure
- Trigger switch sticks or won't lock speed — oxidised speed controller contacts, worn trigger mechanism
- Angle grinder vibrates excessively — spindle bearing play or driven gear deformation
- SDS-Plus chuck on rotary hammer won't hold the bit — worn locking balls or retainer spring
- Circular saw won't reach full speed — stator winding breakdown or electronics overheating
- Jigsaw cuts at an angle — worn guide roller or pendulum mechanism rod play
Bosch Professional vs Bosch DIY line repair
Bosch power tools come in two product lines: Professional (blue housing) for daily professional use, and DIY (green housing) for home users. They differ substantially in construction, which directly affects the nature of failures and the repair approach.
Professional tools feature brushless or high-powered brushed motors, metal gearbox housings, reinforced bearings, and electronics with overload protection. Typical problems under intensive use include: carbon brush wear (in brushed models), gearbox gear tooth wear, spindle bearing degradation, and electronic module failure when working in harsh conditions (dust, vibration). Spare parts for the Professional line are available through Bosch European suppliers and are typically manufactured for many years after a model is discontinued.
DIY tools are simpler in construction: plastic gearbox housings, lower-powered motors, simplified electronics. Failures here more often involve mechanical wear of plastic gears, motor overheating from prolonged operation, and trigger switch or speed controller issues. We repair both lines at the component level at our service centre on Silmaču iela 6.
Bosch 18V and 12V cordless battery rebuild
Battery packs are the most expensive consumable component of cordless Bosch power tools. An original Bosch ProCORE 18V 8.0 Ah battery costs roughly as much as a new budget tool, and many owners of professional kits face the need to replace multiple batteries at once.
We offer an alternative — Bosch battery pack repacking. The process involves: disassembling the housing, load-testing each Li-Ion cell individually, replacing degraded cells with new ones (we use quality cells with verified capacity), inspecting and repairing the BMS (Battery Management System) controller if needed, reassembling, and running a full charge-discharge control cycle. The Bosch BMS controller handles cell balancing, overcharge protection, deep discharge protection, short-circuit protection, and thermal shutdown. If the BMS fails, the battery can stop working entirely even when the cells are healthy — we diagnose and repair the electronics at the component level.
Battery cell replacements carry a 6-month warranty. Bring your Bosch batteries to Silmaču iela 6 — we will restore them to working condition.
Pricing & warranty
Fast on-site diagnostics. Warranty: 3 months.
If the repair cost changes during the process, the technician will call to agree on the new price. No work is done without your consent.
