SKIL PWR CORE 20 6-1/2 in. Circular Saw Kit CR540602: problems, parts and running costs

Checked: 2026-10-08

Summary

The likely failures are the usual budget-cordless ones, straight from SKIL’s own troubleshooting table: a dead or badly seated battery, a burned-out switch, dull or unbalanced blades, and blade slip when the washers are not clamped tight. Running costs are blades plus the battery platform: a replacement 24-tooth blade is $8.99 from SKIL (checked 2026-10), and spare batteries run $44.99 to $89.99. At $94.91 from Acme Tools (checked 2026-10) it is a low-risk way into the PWR CORE 20 platform; above roughly $110, SKIL’s own brushless kits are the stronger buy.

Common problems and fixes

Saw does not start — the manual’s troubleshooting table lists a depleted battery, an improperly installed battery or a burned-out switch [2]. Fix: charge and reseat the pack first; a burned switch is a service job. Warranty: 3 years on the tool, 5 years if registered within 30 days, with blades and other consumables excluded [2][4].
Blade does not come up to speed — the manual ties this to a low battery [2]. Fix: run a charged pack.
Excessive vibration — caused by an out-of-balance blade or a workpiece that is not clamped or supported [2]. Fix: use a balanced blade rated 4,500 RPM or greater and clamp the workpiece.
Blade wanders off the line — dull teeth, a foot that is out of line or bent, or a bent blade [2]. Fix: replace the blade (the manual says replace rather than sharpen) and check the base plate.
Cut binds, burns or stalls the motor when ripping — a dull blade with improper tooth set, blade binding or improper workpiece support [2]. Fix: fresh blade and proper support.
Blade slipping — reassemble the blade and tighten the washers [2].
Overload shutdown — internal sensors shut the tool off and flash the LED when the tool or battery is overloaded or too hot [2]. Fix: let it cool and ease off the feed rate; the PWR CORE 20 battery has a temperature management system [1].
Dull, gummy blades — blades dull and gum up with wood pitch; the manual says wipe them with kerosene or a similar solvent and replace rather than sharpen [2]. Blades sit outside the warranty, so wear is on the owner [2][4].
Battery mix-ups in the box — one retailer shows a 5.0Ah-battery variant under the same CR540602 label, and another retailer’s text reads “20Ah” (a typo of 2.0Ah); check the SKU text before ordering [6].

Parts and consumables

24-tooth 6-1/2 in. blade (CRB1002) — $8.99 from SKIL (checked 2026-10); one ships in the kit [1]. This is the wear item: blades dull and gum up with wood pitch and are replaced, not sharpened [2].
2.0Ah battery (BY519701 / BY519702) — $44.99 from SKIL (checked 2026-10); this is the pack in the kit [1][2].
4.0Ah battery (BY519601) — $79.99 from SKIL (checked 2026-10) [1][2].
5.0Ah battery (BY519603) — $89.99 from SKIL (checked 2026-10) [1][2].
Charger (SC535801) — $69.99 from SKIL (checked 2026-10) [1][2].
PWR Assist USB adapter — $29.99 from SKIL (checked 2026-10) [1].
PWR JUMP charger — $54.99 from SKIL (checked 2026-10) [1].

Replacement intervals: not reported — no owner-discussion set was reachable.

Yearly running cost

Consumables are just blades. A 24-tooth 6-1/2 in. blade is $8.99 from SKIL (checked 2026-10), and the manual says blades dull and gum up with wood pitch and should be replaced, not sharpened [1][2]. Batteries and chargers carry a 2-year warranty, so a failed pack is the next cost — a replacement 2.0Ah is $44.99 [1][2][4]. No electricity or subscription costs are published. A typical annual total: Not enough data.

When it is a good buy

At or below about $95 — Acme Tools had the kit at $94.91 against a $99.99 reference, listed as clearance (checked 2026-10); at that price it is a low-risk purchase for light DIY work and for entering the PWR CORE 20 platform [7].
Between about $96 and $110 — SKIL direct lists the kit at $99.99 (sold out at check), so it stays a reasonable light-DIY buy if you want the battery platform [1].
In Canada, Kent Building Supplies lists the same model at CAD $139.99, out of stock — a weaker value case [5].
